{blackbabes} What's shakin'

Serena Williams shook her stuff on Thursday night at an impromptu performance by her on-again flame Common at the premiere party for "Hell on Wheels." The rapper, who also co-stars in AMC's new drama about a Confederate soldier who seeks revenge on Union soldiers who murdered his wife, took the stage during the after-party Thursday night at Union Station's Harvey House in LA to sing three songs including his latest track, "Hell on Wheels," inspired by the show.
