'Biggest Loser' Trainer Shuffle
"American Idol" wasn't the only show to see significant cast changes. Over at "The Biggest Loser," trainer turnover was sizable. In Season 11, contestants saw boxer Cara Castronuova and fitness expert Brett Hoebel join Jillian Michaels and Bob Harper ... more. By Season 12, of this group only Bob remained. Added to the mix were Dolvett Quince and former tennis pro (and Web search sensation) Anna Kournikova. What can viewers expect next season? More change. Even before the current season was over, the show announced that Kournikova would not be returning for another season. Draw your own conclusions.
