The stars looked g-l-a-m on the red carpet, but it all got a little more rock 'n' roll when they hit the stage last night at the Fashion Rocks concert (remember the magazine supplement with J Lo on the cover?), part of NY Fashion Week. The annual event is thrown by Conde Nast and accompanied by an online charity auction. At the show, Jeremy Piven was MC to, as usual, some awesome on stage combinations - Fergie performed with both Ludacris and Aerosmith while Usher sang alongside Mary J. Blige and so many more. You guys were pretty split on your opinions of Jennifer Lopez's new video for Do It Well, but it looks like she killed it last night. Definitely the highlight judging from the pictures. Don't let these be all you see - check out the show tonight on CBS!
