Step forward Paris Hilton.
The heiress and the model of the moment caused a flurry of flashbulbs from waiting photographers as they left The Gotha Party at 5am.
Cara looked a little worse for wear as she left the bash, flashing plenty of flesh as she went braless with just a blazer over the top.
Paris meanwhile, was having a bit of a fake tan disaster, as he orange legs failed to match the rest of her pale skin, having earlier attended the premiere of 'The Bling Ring', which stars Emma Watson.
British model Cara has been making quite the impression at the festival since jetting in from New York earlier this week.
And with over a week left of the annual film fest left, we can be sure of plenty more antics (and facial expressions) from Ms Delevingne. Hurrah!
