The Hills

Audrina Patridge, the BFF and roommate of Lauren Conrad, will appear alongside the Las Vegas Pussycat Dolls show inside Pure Nightclub on March 28.

The event will celebrate the new season of The Hills, which returns March 24. Not sure if we've mentioned that at any point recently.

Sources say Audrina Patridge will don the skimpy burlesque outfit that the Pussycat Dolls are famous for when she introduces the performers.

What else she might do is still undetermined, but celebrity hosts have sung, danced in a champagne glass, and swung from the ceiling on a swing.

Past hosts include Paris Hilton, Pam Anderson, Eva Longoria, Dita Von Teese and Denise Richards. Pretty good company for Audrina.

No word on whether she'll appear on Pussycat Dolls Present: Girlicious.
