Kate Middleton's gorgeous little sis got all glammed up for the premiere of 'Shadow Dancer' in the capital last night.
But while fellow famous bottom owner Kim Kardashian showed off her behind in a tiny black bikini whilst frolicking on the beach (as you do), Pips kept hers firmly to herself.
The 28-year-old looked demure in a black knee-length dress with a sweetheart neckline and white lace detail.
But although there was no flesh on show, the outline of her famous backside could still clearly be seen. The girl knows how to work it!
And she shrugged off Karl Lagerfield's rather horrible comments recently about her appearance by smiling at photographers as she posed on the blue carpet.
The fashion designer caused a stir last month when he followed his 'fat Adele' comments by saying that Pippa Middleton should hide her face.

He said: "Kate Middleton has a nice silhouette and she is the right girl for that boy.
"I like that kind of woman, I like romantic beauties. On the other hand, her sister struggles.
"I don't like the sister's face. She should only show her back."
Pips put two fingers up at the meanie by taking the attention away from her behind last night as she showed off her pearly whites and gorgeous complexion at the swanky event.
Meanwhile Kim K continue to enjoy her jollies with boyfriend Kanye West in Hawaii - and makes sure she tweets us pictures of her body every step of the way.
