— -- Nastia Liukin is doing back flips now that she's engaged.

The former "Dancing with the Stars" contestant announced Monday night that her boyfriend, Matt Lombardi, had proposed.

"So this just happened..." she wrote, along with a photo of her new diamond ring.

The Olympic gymnast, 25, made it to the semifinals of the ABC reality show. Lombardi, a former professional hockey player, is the co-founder and COO of Venture Up, a web platform that caters to young athletes.

The couple has been together since at least last year.
