The “Velvet Teddy Bear” has had his share of weight loss woes. He dropped 70 pounds in 2006 following a healthy eating program sponsored by Duke University. He maintained his slimmed-down size for years.
His 2011 divorce was a stumbling block for the singer, who told Wendy Williams he started gaining back the weight during the split, partially due to "stress eating."
Studdard, who won Season 2 of “Idol,” will be put to the test by one of the show’s ruthless but loving trainers; Bob Harper, Jillian Michaels or Dolvett Quince.
The new season takes off October 8 on NBC.
“The Biggest Loser” will look a little like “Celebrity Fit Club” this fall when “American Idol” winner Ruben Studdard joins the show, reports Us Weekly.
