Celebrity best friends: The BFFs defining #SquadGoals

Celebrity best friends come in all shapes and sizes. From cool fashion twosomes to Hollywood co-stars, see our favourite famous pairings that fell in platonic love...

From Hollywood greats that met on set decades ago to party pals that have become inseparable, there's nothing like a dose of celebrity best friends to remind you of how much you love your own ladies (or boy BFFs in the case of Drew and Adam).

Just as is the case with us, celeb pairings can be unusual too and we'll bet you there's a couple on this list who you wouldn't expect to be pals. But hey, when you need a friend you need a friend, right?

From long-standing besties like Madonna and Gwyneth and Kate and Naomi, to lesser known friends like Miley and Kelly O, these pairings might surprise you but are sure to warm the cockles of your heart, too.

And of course, Taylor Swift is always out and about with her girl squad, with the likes of Karlie Kloss, Cara Delevingne and Lily Donaldson all seen together with her on a regular basis and no doubt familiar with a few best friend quotes or two. On the West Coast, you can regularly spot Hailey Baldwin, Gigi Hadid and Kendall Jenner all hanging out together too.

Whether you're fascinated by Pixie Geldof and Alexa Chung's sisterly love-in or charmed by the greatest boy-meets-girl-and-they-fall-in-friendship-love partnership of our time - Jennifer Lawrence and Bradley Cooper - we've found plenty of celebrity best friends willing to share their platonic love with the world by way of gorgeous photos.

Most recently though and Manchester By The Sea co-stars Casey Affleck and Michelle Williams have been hanging out, with early reviewers of their new film tipping them both for Oscar success. Allied co-stars Marion Cotillard and Brad Pitt have also been out and about on the red carpet together promoting their new film and shared the sweetest BFF moment in London when they were pictured high-fiving!

Meanwhile Taylor Swift added to her #squad when she was snapped popping out for dinner with Serena Williams and Dakota Johnson in New York in October 2016.

Gwyneth Paltrow, Kate Hudson, Reese Witherspoon and more...

It looks like Gwyneth Paltrow wants people to remember who the original celebrity BFF is.

Talk about #SquadGoals. 

Winona Ryder and Marc Jacobs

90s icon Winona Ryder joined her designer bestie Marc Jacobs at his Velvet Noir event in New York early this week. The actress was recently unveiled as the face of Marc Jacobs beauty campaign, so it looks like these two friends will be seeing a lot of each other in the near future...

Kendall Jenner and Poppy and Cara Delevingne

BFF's Cara and Kendall were most recently seen partying with Cara's older sister Poppy at Eva Cavalli's masquerade birthday party in October 2015 in London. Nothing says 'besties' like matching masks and lipsticks.

Suki Waterhouse and Cara Delevingne

Suki and Cara are a match made in best-friend-heaven. Both beautiful models who herald from London, these two have bags personality, enjoying nights out in strip clubs, music gigs and even posing topless together for a fashion shoot once. 

Alexa Chung and Pixie Geldof

Possibly the coolest celebrity pair going, Alexa Chung and Pixie Geldof give A-List friendships a good name. Always spotted at the hottest hang-outs, always snapping enviable Instagram snaps and always hanging out with the most high profile names in young hot Hollywood. Can we join?

Bradley Cooper and Jennifer Lawrence

Bradley Cooper and Jennifer Lawrence are essentially our dream couple that never was, but I guess we'll settle for the two being insanely close and charismatic in each other's company for the rest of time. Here's to being co-stars FOREVER, guys.

Poppy Delevingne and Sienna Miller

Poppy Delevingne admitted to having a serious girl crush on Brit stunner Sienna Miller before she met her, but now the two are thick as thieves. Not only did the pair live together in New York and have continued to stay close, but Sienna played a big part in Poppy's wild hen 'do last year. 

Johnny Depp and Stella McCartney

Johnny Depp dated Stella McCartney's best girl pal Kate Moss back in the 90s. Now the smouldering A-lister's starring in Stella's dad's latest music video, Queenie Eye. It seems wherever these two close friends go, they end up rubbing shoulders.

Tina Fey and Amy Poehler

Tina Fey and Amy Poehler are one of our favourite celebrity pal pairings. With over 10 years friendship behind them and numerous comedy hits in the bag, it's no wonder these two have incredible chemistry. Room for a third BFF, girls? 

Adam Sandler and Drew Barrymore

Adam Sandler and Drew Barrymore recently re-kindled their on screen antics for new movie Blended, but we'll never forget the hilarious twosome in 50 First Dates. They've got over a decade of 'in' jokes, ridiculous faces and besty-love in the friendship bank, which makes these two Hollywood greats just about the coolest famous comrades in LA.

Kristen Wiig and Maya Rudolph

Kristen Wiig and Maya Rudolph gave us a glimpse into their friendship during 2 of the best hours of our cinema life as we cackled at their chemistry watching Bridesmaids. And their on-screen adoration for each other isn't fake - these two are bonafide best pals.

Katy Perry and Ellie Goulding

Katy Perry and Ellie Goulding are two pop mavens on the party scene that have struck up a genuine friendship. Flying across the pond to support each other's careers is all part and parcel of their days jobs as BFFs. Sweet.

Liv Tyler and Maggie Gyllenhaal

Liv Tyler and Maggie Gyllenhaal have been on the same circuit for longer than we can remember. Growing up in New York, supporting their famous families and becoming stars in their own right are all common ground for these too. Plus, they seem like the nicest best friends on the planet.

Miley Cyrus and Miranda Kerr

Miley Cyrus and Miranda Kerr have recently struck up a close friendship after meeting on the party scene. A few raucous nights later, and these two look like they're building some serious BFF foundations. We'll be keeping a beady eye on this twosome...

Gwen Stefani and Nicole Richie

Gwen Stefani and Nicole Richie have got to be the most stylish celebrity friends in America. Effortlessly cool, totally fashion forward, both with rockstar hubbies and cute kids, we bet it's style-swapping and edgy playdates all the way for these two.

Miley Cyrus and Kelly Osbourne

Miley Cyrus hasn't just been teaching her tongue-wagging skills to Miranda Kerr. No, Kelly Osbourne's also been on the receiving end of Miley's friendship frenzy. We can't help but think these two are slightly better suited as best pals...

Fearne Cotton and Holly Willoughby

Fearne Cotton and Holly Willoughby are two TV darlings that have the nation head over heels in love. And they can share this warm and fuzzy fandom together as both celeb mums are super-close friends. 

Taylor Swift and Kelly Osbourne

Taylor Swift and Kelly Osbourne gave us a glimpse into their platonic love-in with a bit of Instagram action last year. The girls dressed up as 50s housewives and indulged in some dreamy home-baked cookies. Now that's the kind of friendship we're talking about...

Julia Roberts and George Clooney

Julia Roberts and George Clooney are Hollywood greats. And Hollywood greats hang out, because who better to spend your time with than a charismatic bunch of old time A-listers.

Jay-Z, Rita Ora and Beyonce

Jay-Z, Rita Ora and Beyonce are bound to be close. Rita's signed to Jay's music label, Roc Nation, and calls Beyonce "family" so it's only natural the three kick back together and party. We wonder if Rita's on standby for babysitting duties?

Kate Hudson and Anne Hathaway

Kate Hudson and Anne Hathaway may have been rivals in chick flick Bride Wars, but these two glossy Hollywood girls are nothing short of favourites to each other. 

Vanessa Hudgens and Ashley Tisdale

Donatella Versace and Kate Moss

Donatella Versace and Kate Moss are two fashion big-hitters that lean on each other for support. Acting as a mentor, Donatella helped Kate carve out her modelling career and the two have build up a long and lasting friendship as a result. 

Henry Holland and Agyness Deyn

Henry Holland and Agyness Deyn have known each other since the bad hair and brace days (we've all been there), meeting at school when they were 13 in Ramsbottom. Both have blossomed into beauties and taken over the fashion world a storm but stayed incredibly close. We love this BFF coupling.

Victoria Beckham and Eva Longoria

This celebrity pairing have been close for a long time now but they were spotted flaunting their friendship at the Gift Gala in London in November, with Eva even tweeting an intimate snap of the designer doing some last minute alterations to her evening gown. Now that's love.

Gwyneth Paltrow and Stella McCartney

This fashion friendship has taken the next step. Gwyneth Paltrow and Stella McCartney announced a collaboration earlier this year leaving the fashion world desperate to know what these two old friends will be working on.

Lena Dunham and Sarah Jessica Parker

An unexpected friendship, sitcom stars Sarah Jessica Parker and Lena Dunham talk shop at this year's Met Gala. Lena's show Girls has been dubbed this century's Sex and The City so we suspect the pair had plenty to catch up on.

Jennifer Aniston and Courteney Cox

The most famous of Hollywood's celebrity BFFs, former Friends starlets Jennifer Aniston and Courteney Cox struck up a close union on the set of the show in 1994 -  and have inseperable ever since!

Kristen Stewart and Dakota Fanning

Twilight twosome Kristen Stewart and Dakota Fanning struck up a friendship on the famous movie set in 2008 - despite playing opposite sides of the vampire team. The pair later starred in Joan Jett biopic The Runaways together, with Kristen gushing of 16-year-old Dakota: 'She?s become one of my best friends. We?re really close. I think it?s really great working with your friends, and to be completely open with someone and to have no defense mechanism, you know what I mean?' Aww.

Gwyneth Paltrow and Beyonce

With world famous husbands and rocketing careers under their belt, we're surprised Gwyneth Paltrow and Beyonce even found the time to become A-list BFFs. But they did! The twosome often holiday together in the swanky Hamptons, and were spied hitting several UK festivals together this summer. Earlier this year, Bey said of her pal: 'She pushes her boundaries all the time. You go to her house and she makes you feel like you never want to go home,' while Gwynnie let slip Ms Knowles gives her singing advice.

Katie Holmes and Victoria Beckham

Fashion friends Katie Holmes and Victoria Beckham have graced many a front row together, even spending Thanksgiving together with the families in New York. Tom and Katie have been spied watching Becks play football, while Katie was reportedly so jealous Victoria got to attend William and Kate's Royal Wedding she made Victoria promise to call with a report of the day. 'Katie is a great girlfriend,' Victoria spilled of her famous pal. 'We're very girlie together. She really helped me out when we moved to L.A., introducing us to people and finding a school for the kids.'

Kate Hudson and Liv Tyler

They're both from famous families, so best friends Kate Hudson and Liv Tyler know all about growing up in Hollywood. The A-list beauties have been friends for years, and are often spied hitting the red carpet together, or enjoying girlie dinners at one of LA's many swanky eateries.

Gywneth Paltrow and Madonna

One of Hollywood's longest running friendships, Gwynnie once famously referred to Madonna as being 'like an older sister? to her. The pair graced numerous red carpets together and even lived in the same street in London. But rumour has it their friendship is no more. Gwynnie and Madge reportedly fell out over personal trainer Tracey Anderson, and have hardly been seen together since.

Naomi Campbell and Kate Moss

Fashion pals Naomi Campbell and Kate Moss hit catwalks around the world together for over a decade, becoming two of the industry's most famous faces. At one point the pair were inseparable, with Naomi gushing: ?I'm so lucky to have friends like Kate, who are there for me whatever. Even if we're not on the same continent, we support each other. That's what best friends do. We've been through so much together'.

Brad Pitt and George Clooney

They've starred in countless movies together and have had a Bromance that's lasted for years - yes, Brad Pitt and George Clooney must be some of Hollywood's most famous male best friends.

Nicole Kidman and Naomi Watts

'Naomi Watts and I are very, very good friends and have maintained that through so many things,' Nicole revealed in an interview with the Telegraph back in 2008. 'I think that's really rare, particularly for actresses, and I take a lot of pride in that.'

Sienna Miller and Keira Knightley

Style-savvy starlets Sienna Miller and Keira Knighley struck up a friendship on the set of Brit flick The Edge of Love, after Si stepped into a role originally meant for Lindsay Lohan. The super-cute twosome formed a close bond and have often been spied out together on outings around London.

Ben Affleck and Matt Damon

Part one of Hollywood's most famous circle of friends - along with George Clooney and Brad Pitt - Ben Affleck and Matt Damon have been friends since childhood and wrote the Oscar-winning screenplay for Good Will Hunting together.

Salma Hayek and Penelope Cruz

One of Hollywood's most enduring friendships. Salma was the only person Penelope knew when she first moved to the States, and the pair lived together while Cruz filmed her first Hollywood flick.

Liv Tyler and Eva Mendes

Hollywood BFFs Liv and Eva are often spotted out indulging in girly catch ups, from shopping sprees to red carpet love-ins.

Daisy Lowe and Alexa Chung

As two of London's favourite IT girls, it?s no wonder that Alexa and Daisy mates. They are often spotted catching up at the capital's swankiest bashes and endless fashion parties.

Kate Moss and Kelly Osbourne

Kelly and Kate have been painting London town red since first meeting back in 2006 and have remained firm friends, with Ms O attending the supermodels 2011 wedding, later commenting it was ' the most beautiful, loving, amazing wedding I have ever been to.'
