The weight-loss competition draws to a close with a two-hour finale tonight that will see siblings Hannah and Olivia battling with either Jay or Irene for the $250,000 prize and title of 'The Biggest Loser'.
"This season is anyone's game," said Sweeney during an appearance on NBC's Today Show this morning, where she was asked to handicap the finalists.
Hannah and Olivia are the first sisters to have earned places in the final, having shed 98lbs and 108lbs respectively on the ranch. "They are both amazing women," said Sweeney. "Olivia is the older sister and has a little bit of an edge, she's won more challenges and a lot of weigh-ins, but Hannah brought it out at the end and won the last challenge and weigh-in."
The result of the public vote to decide whether the siblings will be joined by Jay or Irene in the battle for the prize will also be revealed tonight.
Jay was initially eliminated from the ranch during episode seven when he fell below the yellow line with daughter Jen and asked the players to send him home instead. He returned in episode 12 to fill an extra space on the Blue Team.
Sweeney told Matt Lauer and Ann Curry that it would be a close race between Jay and Irene, who had the highest percentage of weight-loss on campus and was nicknamed "silent ninja" by the cast and crew.
The winner of the at-home prize will also be crowned.
The Biggest Loser concludes tonight at 8/7c on NBC.
