Christina Aguilera and Kim Kardashian: Bionic Babes

Continuing her celebration of her new album Bionic, Christina Aguilera held a release party at the New York City hotspot AVENUE last night (June 9).

The “Ain’t No Other Man” songstress looked amazing in an all-black ensemble with Stephen Webster jewelry as she hung out behind the deejay booth.

And it was quite the star-studded affair, with guests like Serena Williams, Selita Ebanks, and Kim Kardashian all in attendance.

Christina has been working overtime to promote her new album, performing on the “Today” show and “The Early Show” this week.
