Clarkson won two Grammy awards on Wednesday night in Los Angeles: Best Pop Vocal album for "Breakaway" and Female Pop Vocal performance for "Since U Been Gone."

Accepting those awards, the 23-year-old Clarkson thanked everyone from the musicians who performed on her album to radio itself. "American Idol," however went unmentioned.

Backstage at the Staples Center, she defended the omission: "I did thank the fans and that's `American Idol.'"
