Ruben Studdard stole the hearts of Americans everywhere after winning the second season of American Idol back in 2003. Now, the crooner, known as the “Velvet Teddybear,” has decided to give reality television another shot. But this time he won’t be showing the world his vocal skills, instead, he’s attempting to win big on NBC’s The Biggest Loser.
The balladeer may be the most high-profile contestant this season, and weighing in at 462-pounds, he is definitely the heaviest.
