Michelle Aguilar won the most recent season of The Biggest Loser.

But that wasn't the best thing to happen to this reality TV star over the last couple months:

Nine days after she was declared champion, Aguilar's boyfriend of four months, Matthew Whitehead, proposed.

"I was so shocked!" Michelle told Us Weekly.

The 27-year-old Aguilar - who lost an 110 lbs. during the series - is relieved that shopping for a wedding dress will be "absolutely liberating."

"Before, you have that fear: 'Hey, can you pull me a size 20?'" said Aguilar, who is now a size 4 to 6. "What girl wants to say that?"

Michelle Aguilar feels peaceful.

The winner of this season's The Biggest Loser told Us Weekly that she's calmer than ever.

"It's funny, but I feel at peace," she said. "I mean, I'm excited on the outside, but I also feel a real calm, like I'm fulfilling something that I was meant to fulfill -- and that feels great! I feel like this world is now my oyster, and I'm just going to go after it!"

Aguilar added that she isn't worried about packing on the pounds again now that she's off the show.

"I've got the greatest support team back home in my family. They serve as a constant reminder to me every day... I'm so lucky to have such a great family. I truly cherish them."

Michelle Aguilar conquered all competitors last night on The Biggest Loser: Families. And she didn't hide her emotion after being named champion.

"I'm number one!" Michelle screamed, as the season's 15 other contestants congratulated her and confetti streamed down on the finale stage.

Aguilar, a 26-year-old assistant director from Ft. Worth, Texas, began the competition at 242 pounds and lost 132 pounds, sufficient for a 45.45% weight-loss percentage. She earned the show's $250,000 grand prize for her efforts.
