The Biggest Loser Thanksgiving Celebration

S12, E11: In this inspiring Thanksgiving special unlike any before on "The Biggest Loser," viewers can catch up with some of their favorite contestants ever, but they'll also be treated to never-before-seen footage and -- for the first time ever -- hilarious bloopers featuring the trainers, host Alison Sweeney and the contestants. And trainers Bob Harper, Anna Kournikova and Dolvett Quince will all be on hand to share their thoughts about the current season of the show. Fan favorites like Abby Rike, Tara Costa, O'Neal Hampton and season five winner Ali Vincent will reveal what they're up to now, along with season eight champ Danny Cahill, season 11 winner Olivia Ward, and other popular players. One contestant makes a big surprise announcement, and cameras will also follow trainer Bob Harper through "a day in the life." Plus, cooking expert Aida Mollenkamp will prepare a healthy Thanksgiving feast for the trainers and past season contestants, and share great cooking tips as well. Alison Sweeney hosts the special.
