She's one of the leading stars in the brand new big-screen version of Peter Pan. And as Cara Delevingne attended the world premiere of 'Pan' in London on Sunday afternoon, she made sure all eyes were on her on the red carpet.

The 23-year-old was so excited to premiere her new film in London, that she jumped up on the barricade on the red carpet to say hello to her adoring fans. But in her attempt to do so, her cute minidress rode up way too far in the back, showing her entire butt to everyone behind her.

From kicking it in a khaki camouflage jacket to glamming it up in a power LBD, the model always knows how to turn heads. For the Pan premiere in London she wowed again in a head-turner of a dress which she styled with caged booties.

Cara Delevingne opted for a thigh-skimmingly short LBD with a soft feather effect across the skirt, chest and on the capped sleeves.

Adding a racier edge to the look, the sexy little number included sheer panels, giving a glimpse at her trim waistline and shoulders.

Her dark blonde locks were swept up into a high ponytail with twists of plaits running across her scalp, and she rocked a sultry smokey eye in terms of her make-up.

The model turned actress knows how to make a statement on the red carpet, and the Pan premiere was no exception! It seemed like the sheer panels on her waist, back and collar would be the most revealing her outfit would get, but everyone really got a surprise as she showed off more than she expected.

When she saw fans who had been waiting for hours to catch a glimpse of her and her famous costars at the Pan premiere, she ran over to say hello and give autographs. Unfortunately, hoisting herself up on the railing caused a major wardrobe malfunction. Her super-short dress raised up over her butt, and flashed it all to everyone on the red carpet.

Those in front of her clearly had no idea that Cara was inadvertently flashing herself - pretty much every inch of her lithe legs on show - as they chatted away to her, but those behind her got a full viewing of her bare butt.

Pan is tipped to be one of the biggest movies of the year, and is a reworking of the iconic Neverland-based fairytale.

It stars Australian hunk Hugh Jackman as leading man Blackbeard, with Cara portraying a mermaid. Rooney Mara takes on the role of Tiger Lily, Garrett Hedlund plays Hook, and Peter Pan has been brought to life by young up and coming star Levi Miller.
