While he certainly wouldn't be alone, Rolling Stones frontman, Mick Jagger, had admitted he's addicted to Facebook. The 68-year-old singer says he spends way too much time online looking up old friends. Jagger told the Britain's Daily Express that Facebook was effecting his music:

"I spend way too much time on the computer and not enough time playing the guitar."There's an underlying problem of this screen life taking over all of your life. It's easy to keep in touch with people, some of whom I wish I'd never kept in touch with. But there they are on Facebook." - Contactmusic.com

Jagger's addiction is something that has developed fairly recently. Jagger admitted last year that he hired a personal assistant to update his online blogs because he couldn't keep up with the technology.
