Jillian Michaels is Engaged - Watch Proposal to Heidi Rhoades!

Jillian Michaels is engaged to her longtime partner Heidi Rhoades!

The 42-year-old former The Biggest Loser trainer popped the question on the season finale of her E! reality show Just Jillian.

Jillian proposed by playing a video montage showing their relationship and it ended with friends and family holding up the words “Will you marry me?” on signs.

“I know I’m an a–hole all the time, but if you’ll continue to put up with me, I would like you to marry me,” Jillian said as she got down on one knee.

“Heidi is the perfect person for me. The only place where there’s like a solace…a safe-haven is with my family,” Jillian said in her commentary. “And Heidi is the nucleus of that family. She’s the glue that really holds everything together and I think without that, I would be lost.”

Jillian and Heidi have two children together – a daughter named Lu and a son named Phoenix.
