Plus, Contestants Are Surprised By Loved Ones in Heartwarming Reunions!

UNIVERSAL CITY, CALIFORNIA � November 25, 2008 � It's one of the most eagerly-anticipated events of every "Biggest Loser" season � the makeover episode! And this season, Tyra Banks and "Project Runway" winner Christian Siriano will be on hand to help reveal the amazing transformations on NBC's "The Biggest Loser: Families" airing Tuesday, December 2 (8-10 p.m. ET).

First, the remaining five contestants are whisked away to New York City for incredible makeovers that will show how far they've really come in their weight-loss journeys. After getting new hairstyles at a top salon, the contestants are off to Macy's, where "Project Runway" winner Christian Siriano helps them pick out new outfits to show off their skinnier new figures. Then they head to the "Tyra Banks Show," where Tabatha (Bravo's "Tabatha's Salon Takeover") works her magic to help complete their transformations. Finally, the made-over contestants are revealed on the "Tyra Banks Show," unaware that their loved ones are waiting to surprise them once they walk out on the stage!

After emotional reunions with family members, the contestants get to enjoy a day in New York with their loved ones before heading back to the "Biggest Loser" ranch. There, host Alison Sweeney introduces them to their next challenge, where they'll have to wedge themselves inside glass cubes hanging 15 feet above the water for as long as they can without falling. It's a wild competition that becomes a huge victory for one player struggling to over come her fears. Then it's time for the weigh-in, and a tough elimination round that will send another player home.

A special "Biggest Loser" episode of the "Tyra Banks Show," featuring additional footage from the contestant makeovers, will air Wednesday, December 3 (check local listings for air time).
