Justin Timberlake

Justin Timberlake has crammed an impressive amount into his 12 years in the 'biz. He found fame as a Mousketeer, lead singer of 'N Sync and Britney's other half before promising to "bring sexy back" in his solo career. Music aside, he's managed to start a charitable foundation, launch his own clothing label, branch out into acting and work on his golf handicap, as well as step out with Hollywood stars such as Cameron Diaz and Jessica Biel.

But did you know that Justin's famously curly hair was the bane of his life during middle school. He recalls: "That was the thing everybody teased me about. They called me brillo pad. I was always trying to either straighten the crap out of it or cut it all off. In second grade I took like paper scissors and cut my hair all uneven... That's the only time I ever really got a spanking."
