Remember Ruben Studdard? He found his 15 minutes of fame as the winner of American Idol - Season 2. He hasn't made a lot of noise since then, although he has been recording, touring and acting. In fact, he released an album just last year. But now he's on to something a little different. "The Biggest Loser" Ruben has struggled with his weight through the years. He also has a family history of high blood pressure and diabetes. So, he feels that it's especially important for him to lose the weight before he has to deal with any of these health issues.

Ruben will be the first celebrity to compete in "The Biggest Loser" and you can follow his weight loss journey in season 15 this fall. Good luck Ruben!
