This week of American Idol will add one more name to its already stellar line-up of celebrity appearances: fab singer-songwriter Sheryl Crow. According to an anonymous source who talked to E!Online, Sheryl will appear this week as a musical mentor for the Idol Top 5. Said the source, “The show wanted Sheryl because she is a true singer-songwriter and she wanted to help them develop as artists.”

However, adding interest to Crow’s Idol appearance is the fact that she hasn’t always been a fan of the show. During a 2007 interview with MSNBC, Sheryl said, "Let's face it, [American Idol] undermines art in every way and promotes commercialism. I am sad people love it so."

Glad she changed her mind!
