Mariah Carey, Beyonce, Mary J. Blige, Rihanna, Fergie, Sheryl Crow, Miley Cyrus, Melissa Etheridge, Ashanti, Natasha Bedingfield, Keyshia Cole, Ciara, Leona Lewis, LeAnn Rimes and Carrie Underwood have lent their voices to the new song "Just Stand Up," which will be released on September 2. All of the song's sales will be donated to cancer research.

What's even more impressive is that all 15 singers will share the stage to perform the song live on September 5 during the "Stand Up to Cancer" television special, which will air on ABC, NBC and CBS.

Other stars to appear in the special include Christina Applegate (who just recently went public with her own cancer battle), Jennifer Aniston, Charlize Theron, Lance Armstrong, Katie Couric, Sally Field, Salma Hayek, Meryl Streep, Forest Whitaker and Reese Witherspoon.
