Hollywood's elite were out in force for W Magazine's pre-Golden Globes party at the Chateau Marmont hotel on Friday night.
But Cara Delevingne still couldn't help showing off her wild side as she cheekily photobombed a stunning-looking Naomi Campbell.

There's Naomi, trying to take a pretty picture with Chiltern Firehouse owner Andre Balazs, when Cara rocks up at her side and sticks her tongue out, as well as pulling some weird facials.
Naomi didn't seem too bothered, but who would be when you look that good in a plunging gold Emilio Pucci jumper dress with overknee black suede boots. Sigh.
And, in fact, Cara herself looked pretty sexy in a white cutout Tom Ford number when she stopped pulling silly faces.
The star-studded party followed a 'Best Performances' theme and, as such, was packed with some of the current hottest actors in Hollywood.
