A Rocawear Celebration

Last night celebs came out in full force to celebrate Rocawear's fall campaign, which stars Melanie Fiona and Trey Songz. It seems like everyone was there, from Jay-Z, Kanye West and the stars of the campaign to Jay's sister-in-law Solange, Common, Serena Williams (are they still together?), and Selita Banks. Oh, Omarion was there too. What in the hell is he wearing?
