David Guetta

David Guetta, often referred to as the man who brought dance music to American mainstream radio, got his big break when Kelly Rowland saw him DJ in Cannes, France. They got together and recorded "When Love Takes Over," and from there, Guetta's career took off as Rowland helped spread the word.

"I Gotta Feelin'," by the Black Eyed Peas samples Guetta's "Love Is Gone."

When The Sun asked him what he likes to do in his free time, Guetta answered, "This is going to sound crazy but my hobby is music, that's what I do to relax. I'm a DJ so when I relax, I make tracks!"
