LeAnn Rimes and her songwriter husband Dean Sheremet are saying goodbye to their home just outside Nashville, people.com reports.

“LeAnn and Dean’s home is on the market,” the singer’s rep confirms of the $7.45-million US property, which was completed in 2008 and features six bedrooms, 7-½ bathrooms, plus exercise and media rooms.

The decision to sell is not related to reports that Rimes, 26, allegedly had an affair with her Lifetime TV-movie co-star Eddie Cibrian, 35, a friend of the country singer tells People.

Rimes and Sheremet, 28, are committed to their relationship, which has its ups and downs, says Rimes’ friend. “(LeAnn and Dean) are still having challenges and trying to work through them. They’re working on their marriage.”

On Sunday, Rimes was spotted chatting with Cibrian, 35, who’s married to model Brandi Glanville, 36, at a Los Angeles Lakers basketball game. Her pal says it was not a planned meeting.

“That was totally random,” says the friend. “They both just happened to be at the game.”
