Michelle Aguilar

Less than 2 weeks after being crowned The Biggest Loser: Families champ, Michelle Aguilar gained another title: Bride-to-be.

The 27-year-old winner who shed 110 pounds, told Us Weekly she was "shocked" when her boyfriend of less than 4 months, Micah Whitehead, popped the question. So what's it like dress shopping after dropping seven sizes? "Absolutely liberating," Aguilar said. "Before, you have that fear: 'Hey, can you pull me a size 20?' What girl wants to say that?"

The Season 6 winner plans to use some of her $250,000 winnings to pay for the wedding that will most likely take place in spring or fall of 2009.

You can catch the new season of The Biggest Loser: Couples on Tuesdays at 8pm/ET on NBC.
