Fall Out Boy, Jennifer Lopez, Fergie, Usher are among the artists scheduled to perform at the fourth annual Fashion Rocks Concert celebrating the relationship between music and fashion in New York City in Septemeber.

The show will be held on Sept. 6 at Radio City Music Hall, and will air on September 7th in a two-hour special on CBS.

”The synergy between fashion and music is even more pronounced now than it was when we first created Fashion Rocks three years ago,” said Richard Beckman, president of Conde Nast Media Group. ”Each year the line between the two becomes increasingly blurred as more musicians launch fashion lines and more designers align themselves with musicians.”

Avril Lavigne, Carrie Underwood and Santana are also scheduled to appear at the New York Fall Fashion Week event.
