A wide array of A-list acts including Aerosmith [ tickets ], Jennifer Lopez [ tickets ] and Martina McBride [ tickets ] have been tapped to play September's Fashion Rocks [ tickets ], which is part of New York's Fashion Week.

The fourth annual event will take place Sept. 6 at Radio City Music Hall with additional performances by Alicia Keys [ tickets ], Avril Lavigne [ tickets ], Carrie Underwood [ tickets ], Fall Out Boy [ tickets ], Fergie [ tickets ], Jennifer Hudson [ tickets ], Ludacris, Santana and Usher.

The show will be hosted by actor Jeremy Piven, who co-stars in the HBO series "Entourage," and will air as a two-hour special on the CBS network Sept. 7.

"The synergy between fashion and music is even more pronounced now than it was when we first created Fashion Rocks three years ago," Richard D. Beckman, president of event producer Conde Nast Media Group, said in a statement. "Each year, the line between the two becomes increasingly blurred as more musicians launch fashion lines and more designers align themselves with musicians. Fashion Rocks 2007 will feature outstanding performers from both worlds who span the spectrum of musical genres and fashion styles and bring to life that special relationship."

The Fashion Rocks magazine will also return in September, with Vogue Editor-in-Chief Anna Wintour and Contributing Editor Jonathan Van Meter taking the helm.
