Carrie Underwood Records for Charity

What a line-up!

Mariah Carey, Beyoncé, Mary J. Blige, Rihanna, Sheryl Crow, Melissa Etheridge and more musical women are all on the list to record "Just Stand Up" for the Stand Up To Cancer charity effort.

And now, country powerhouse Carrie Underwood has also joined her voice to theirs.

Proceeds from the song, produced by Kenny "Babyface" Edmonds and Antonio "L.A." Reid on sale exclusively on iTunes, will go to the charity.

“It seems that everyone has been touched by cancer these days, whether it be a personal experience, a family member or friend, or their families,” says Carrie.  “If by participating in this charity effort I entice just one person to give funds for cancer research, then it will be so worthwhile.”

The all-female lineup will also debut the song during the Stand Up To Cancer fundraising event, broadcast commercial free simultaneously on ABC, CBS and NBC on Sept. 5.
