Mariah Carey, Justin Timberlake, Beyonce and Rihanna will perform at the fifth annual Fashion Rocks concert celebrating the relationship between music and fashion.
 
The event will be held Sept. 5 at Radio City Music Hall, and will air in a two-hour special on CBS the following night. Proceeds will benefit Stand Up to Cancer, a program established by the Entertainment Industry Foundation to raise money for cancer research.

Also performing: Keith Urban, Chris Brown, Kid Rock, Fergie, Lil Wayne and the Black Eyed Peas.

“Fashion Rocks uniquely celebrates the intersection of two of the most sexy cultural paradigms: fashion and music. This year, we have a spectacular lineup of talent and performances that will take the show to a whole new level,” Richard Beckman, president of Conde Nast Media Group, which produces the event, said.
