Robert Pattinson throws a star-studded birthday party at Claridge’s

The Twilight heart-throb was joined by the likes of Sienna Miller and Tom Sturridge to celebrate his 26th birthday

Robert Pattinson celebrated his 26th birthday in style yesterday by throwing a glitzy party at Claridge’s hotel for his closest family and friends.

The London venue was wall-to-wall with actors including best pal Tom Sturridge, who was accompanied by his pregnant fiancée Sienna Miller. The mum-to-be, who was sporting some new light brown locks, looked as chic as ever dressing her growing baby bump in a stretchy marl grey dress and black blazer, accessorised with open-toe boots and the new Mulberry Del Rey handbag.

Musician friend Marcus Foster, who has often played gigs with Rob and girlfriend Kristen Stewart in the crowd, was also spotted making his way through the hotel to the bash, as was Australian actor Hugh Jackman.

The Twilight heart-throb’s proud parents, Richard and Clare, were next to arrive at Claridge’s for the party, along with the actor’s sisters, Lizzy and Victoria, who were snapped carrying a clutch of wrapped presents.

As for the birthday boy, he was pictured running into the posh venue dressed in his signature relaxed style – black jeans, hoodie, trainers and a baseball cap – but there were no snaps of Kristen, who we presume sneaked in through another entrance to avoid the awaiting paparazzi.

The couple are reportedly back in London following a romantic mini-break together in the Sussex countryside last week, where Kristen was busy with press duties promoting her new film, Snow White and the Huntsman, at the region's Arundel Castle.

Happy birthday for yesterday Rob!
