Justin Timberlake will perform at this year's Fashion Rocks, the Condé Nast benefit for cancer that kicks off on September 5. What else happens then? The start of Mercedes-Benz Fashion Week in New York City. Though JT has been scarce in front rows before, he may want to build his fashion cred now that he's the new face of Givenchy, and the backing behind sportswear label William Rast. And let's not forget that some brands pay very big money to get "fans" to attend their catwalks - and Miss Sixty, Rock & Republic, and Y-3 have a track record of getting crazy flashbulb moments at their shows, and let's not forget Calvin Klein and Tommy Hilfiger. Oh and one more thing - Joe Zee used to be Justin Timberlake's stylist before he went to ELLE. Wouldn't it be good PR for the magazine and it's flagging website if Justin showed up with the boss for a front-row appearance?
