Dean Sheremet is the onetime backup dancer -- now a chef at New York hot spot Nobu 57 -- who married country singer LeAnn Rimes in 2002 and divorced her earlier this year, after news broke that his wife had fallen in love with married actor Eddie Cibrian during a 2008 TV movie shoot.

With months of sordid headlines behind him, Sheremet is officially moving on. The 29-year-old has just gotten engaged to his live-in girlfriend, fashion photographer Sarah Silver. The two are planning a summer wedding, according to Us.

Rimes' ex reportedly popped the question to his 28-year-old fiancee Friday morning, presenting her with a three-carat, antique 1950's ring.

"She is an amazing, talented woman," Sheremet told Us readers in July about his new love, a few weeks after his divorce was finalized. "We have a lot in common and we are both very happy."

And LeAnn Rimes, via Twitter, says she has nothing but happiness for them.
