Four months after reports surfaced that LeAnn Rimes and Eddie Cibrian were allegedly having an affair, a source tells People that the country singer is no longer living with her husband, Dean Sheremet.

“LeAnn and her husband have been separated for quite some time now, but they continue to try and work through their relationship,” a Rimes pal says.

The couple married in 2002, when she was only 19. Last August (six months before their seventh anniversary), they threw a “Seven-Year Itch” party to, as Rimes put it, “remember how blessed we are.”

News of their separation comes days after Cibrian’s wife, Brandi Glanville, said she and the actor were splitting.

“Eddie is a devoted and loving father first and foremost and the speed bump he and Brandi are experiencing needs to be worked out privately for everyone’s benefit,” his manager said in a statement.

Cibrian, 36, who is joining the cast of C.S.I. Miami this fall, has denied he was having an affair with Rimes, his costar in the Lifetime original movie Northern Lights, which they filmed last fall.

In March, the Rimes pal confirmed the singer and Sheremet were having problems in their marriage, but maintained Cibrian was “not the cause,” adding, “There have been issues brewing for months prior to meeting Eddie on set.”

The couple’s Nashville home is currently on the market for $7.45 million.
