Channeling Celia: You're left wondering after the show how long Jennifer Lopez prepared for her Celia Cruz tribute. Lopez was sexy and dazzling, leading a troupe of two dozen dancers through complex routines without missing a step in salute to the Salsa legend. She changed outfits on stage twice, finishing with a shimmering silver singlet and wining triumphantly at the crowd as her dancers sprawled about her at the end of the tribute.
