Michelle Aguilar lost 110 pounds and gained a fiancé. Not a bad trade-off.

The newest winner of The Biggest Loser has gotten engaged to her boyfriend of just four months, Micah Whitehead, accepting his proposal just nine days after taking home the $250,000 grand prize last month.

"I was so shocked!" the bride-to-be told Us Weekly of the proposal, adding that she "absolutely" plans on using some of her hard-won prize money on her big day.

The 27-year-old Aguilar plans to walk down the aisle this spring or fall, and is already pumped at the prospects of shopping for dresses in a single-digit size.

"Before, you have that fear: 'Hey, can you pull me a size 20?' What girl wants to say that?" the now 132 pound, size 4 told the magazine.

The seventh season of the reality hit, The Biggest Loser: Couples, kicked off last night.
