NBC has announced that home viewers will have the opportunity to determine one of The Biggest Loser: Couples' three finalists immediately following the reality weight-loss series' penultimate fifth-season broadcast on Tuesday, April 8.

The Biggest Loser: Couples' remaining four contestants -- Alison Vincent, a 32-year-old hair stylist from Mesa, AZ; Kelly Fields, a 38-year-old nurse from Titusville, FL; Mark Kruger, a 35-year-old aerial device sales representative from Dartmouth, MA; and Roger Schultz, a 40-year-old associate athletic director from Enterprise, AL -- will all participate in the penultimate weigh-in, with the two that post the week's lowest weight-loss percentage being below the yellow line.

However instead of the two contestants above the yellow line voting to determine which contestant is eliminated, host Allison Sweeney will reveal that -- for the first time in The Biggest Loser history -- home viewer votes will determine the show's third finalist.

Immediately following the conclusion of the penultimate episode broadcast at 10PM ET, home viewers will have a 48-hour window to vote via NBC's website for one of the two contestants below the yellow line. 

The contestant who receives the most home viewer votes will then be revealed during the first five minutes of The Biggest Loser: Couples' live finale broadcast on Tuesday, April 15 at 8PM ET/PT.

After the identity of the third finalist is revealed, all three finalists will participate in one last weigh-in and the finalist who posts the highest weight-loss percentage since the start of the competition will claim the show's $250,000 grand prize.  In addition, the previously eliminated contestant that posts the highest weight-loss percentage since the start of the competition will be crowned the fifth-season's "at home" champ and receive a $100,000 consolation prize.
