It was an emotional moment for ALISON VINCENT on Tuesday night's "The Biggest Loser" when she learned that she made it to the finale -- and ET has footage recapturing her excitement! It was an incredible 11-pound weight loss that kept Ali above the yellow line and assured her a place in the final competition.

"When my mom sees this weigh-in, she will probably fall out of her chair," she declares. "In week four, I said, 'I am going to be the Biggest Loser.' When I said it, I meant it and I have never stopped believing it.

Also making the finals based on her weight loss was KELLY FIELDS. This season, in a new twist to the game, America will decide who the third finalist will be by voting online. They will chose between the two "Losers" -- MARK KRUGER and ROGER SCHULTZ -- who fell below the yellow line on Tuesday night's episode.

"Every season we are looking to keep it fresh," executive producer MARK KOOPS told ET last week. "We really felt that after this journey all four were deserving of an opportunity to make it to the finale. What better way than to let the fans who have followed the incredible tales of transformation over 15 weeks have a voice in that process?"
