Carrie Underwood, LeAnn Rimes and Miley Cyrus are among over a dozen female artists joining forces on an unprecedented charity single for breast cancer research! The song, "Just Stand Up," will also feature Sheryl Crow, Melissa Etheridge, Mariah Carey, Mary J.Blige, Rihanna, Fergie, Ashanti, Natasha Bedingfield, Keyshia Cole, Ciara and Leona Lewis. It will be available for purchase exclusively through iTunes beginning September 2, with proceeds going to the "Stand Up To Cancer" campaign. Three days later, on Friday, September 5, the women will perform the tune together on TV for the first time during a star-studded fundraising event titled /Stand Up To Cancer/, which will be broadcast simultaneously on ABC, CBS and NBC. "Just Stand Up" was produced by Kenny "Babyface" Edmonds and Antonio "L.A." Reid.
