NEW YORK (AP) - 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 Tuesday.

Fashion Rocks magazine will also return for its annual issue. The magazine, helmed by Vogue Editor-in-Chief Anna Wintour, will accompany the September edition of 16 Conde Nast magazines.
