American Idol producers convinced reluctant rocker Slash to mentor contestants on the TV singing competition by handing over complete control of their upcoming rock-themed week.
The former Guns 'N' Roses star will advise the final four hopefuls on this week's Rock Week.
And Slash admits he was a skeptic even after other high-profile entertainers -- including filmmaker Quentin Tarantino and actor/singer Jamie Foxx -- served as mentors this season.
He writes on his MySpace blog: "I was reluctant at 1st, but they offered me the freedom to do it however I wanted. More importantly, there are a few singers this year who are really impressive. It's the 1st time any AI line-up has really caught my attention... Those AI kids can sing their a**es off."
