Fame has gotten ugly for American Idol David Cook, who pleaded for privacy while on tour, people.com reports.

“The efforts by some fans to find our hotel rooms, call our hotel rooms, attach things to our bus, etc., is something I have to condemn,” he says on his MySpace blog.

“Should this behavior continue, the only thing we can do is take more preventative measures to maintain our privacy, which in turn makes us less accessible to you.”
