The Hills has its share of catfights, but now it will have a bona fide feline on its hands.

Lauren Conrad‘s trusty sidekick Audrina Patridge will take the stage alongside the Las Vegas Pussycat Dolls show inside Pure Nightclub on March 28 to celebrate the new season of The Hills.

Sources tell PEOPLE that Patridge will don the skimpy burlesque outfit that the Dolls are famous for to introduce the performers. Exactly what else she might do has yet to be determined, but previous celebrity hosts have sung, danced in a champagne glass, and swung from the ceiling on a swing.

Past hosts include Paris Hilton, Eva Longoria, Pam Anderson and Denise Richards.
