LeAnn Rimes and Dean Sheremet: Divorcing

This story basically, legally confirms what we've already known was the case for half the year: It's over for LeAnn Rimes and husband Dean Sheremet.

"After much thoughtful mutual consideration, Deane and I have agreed to move forward with dissolving our marriage," the country star says on her Web site.

"This decision was amicable and we remain committed and caring friends with great admiration for one another. Thank you for your continued love and support."

Rimes, who turned 27 Friday, married Sheremet in 2002 when she was 19 and he was 21. They separated amid allegations of her affair with actor Eddie Cibrian.

LeAnn and Eddie met while filming Lifetime movie Northern Lights last fall. Cibrian, meanwhile, filed for divorce from wife Brandi Glanville last week.

Cibrian's ex has called him "somebody I don't know" and claims she sensed the attraction between the two when they filmed Northern Lights last fall.

Dean Sheremet and LeAnn Rimes were all smiles just a few months ago.

LeAnn and Eddie Cibrian have since gone public with their relationship.

Rimes's longtime friend, Jeff Berger, says that Rimes and Sheremet, a songwriter and former dancer, are "doing their best to handle it as mature adults."

"Dean's her best friend and that's the crux of the issue; when you love and care about somebody who's your best friend – how not to cause pain," he says.

"Le and Dean are great people and, unfortunately, going through a tough situation. But they're doing what needs to be done as amicably as possible."

Dean Sheremet, a former professional dancer, is attending culinary school in NYC. He posted this on Twitter: "Back to school kids, first time in 10 years."
