Socialite Paris Hilton celebrated her 27th birthday with a raunchy performance alongside burlesque revue the Pussycat Dolls on Saturday night.

The hotel heiress, who turned 27 on Sunday, wowed onlookers by gyrating on stage in a succession of skimpy outfits in the Pussycat Dolls Lounge at Caesar's Palace in Las Vegas.

Hilton spent last week rehearsing her sexy dance routine after admitting she was "nervous" at the prospect of embarrassing herself on stage.
