Few female groups can sing and dance with as much sex appeal as the Pussycat Dolls.  And last night Nicole Scherzinger and the girls gave a very special performance at the Fashion Rocks pre-party.

The night was full of energy as the PCD troop took the stage, sporting plenty of skin-tight leather, vinyl, and spandex as they sang through their catalog of hits.

And just think- they were getting everyone ready for the big Fashion Rocks event set to take place later tonight (though it doesn’t air until Tuesday, September 9th) at NYC’s Radio City Music Hall.

This year’s Fashion Rocks extravaganza promises to be the best one yet, with performances from Justin Timberlake, Rihanna, Mariah Carey, and Beyonce Knowles.
