Kate Hudson Is A Hot Mess Wearing Tiny Pink Dress And Fishnets At 36th Birthday Party With Jessica Alba

The usually polished actress is almost unrecognisable as she celebrates getting older by throwing a star-studded themed bash.

Kate Hudson is one celebrity who doesn't seem at all fazed about getting older.

In fact, the actress was so chilled out about turning 36 earlier this month that she decided to throw a fancy dress bash with a couple of pals on Sunday.

'No better way to celebrate a Bday then having a joint 'Hot Mess' themed party with @derekblasberg and @jenmeyerjewelry,' Kate told her Instagram fans.

'And let me tell ya, there were some very committed hot messes last night ;) Such fun! Love you guys ?.'

Kate's words were accompanied by a funny snap which sees the A-lister and her mates rocking some pretty dodgy ensembles.

The usually perfectly polished celeb sports a messy mane of hair and shows off a bright pink thigh-skimming dress featuring saucy cut-outs down either side.

Kate's full outfit - which included neon fishnets, a fluffy cream jacket, a patterned bikini top and a baseball cap - was revealed in another shot.

The Almost Famous star completed her costume with luminous nail varnish and smoky eye make-up.

Even though she totally pulled it off, we're pretty sure we won't be seeing Kate recreating this, erm, interesting look on the red carpet anytime soon.

Can you imagine what would happen is she donned it for the Oscars?!

A number of VIPs were invited along to the blonde's bash including Jessica Alba, who posed for a sweet picture with Kate's co-host Derek.

'The party theme was 'Hot Mess.' (@jessicaalba was hot. I was a mess.),' the fashion writer quipped alongside an image posted to his own account.

Derek, 33, flashes a broad smile in a red and black spotty shirt as Cash Warren's 34-year-old wife nestles in close for a hug.

Mum-of-two Jessica appeared to play it safe wearing a black strappy design.
