LeAnn Rimes and husbandÑit may be over

In what would appear to be a never-ending train of celebrity tragedies and splits, country singer LeAnn Rimes and her husband, Dean Sheremet, have separated, reports Us Weekly. No statement has been made as of yet that would allude to a divorce in the works, but a source says of the couple, "They are leading separate lives and not staying together most of the time, but still live in each other's lives as best friends."

Many have been speculating that the reason for the separation, which has been going on quite a while now, is because rumors saying that Rimes has been continuing an extramarital affair with her costar on the Lifetime network, Eddie Cibrian. Apparently, the two were spotted sharing an intimate dinner and spent time in Malibu in March alone together. On Thursday, Rimes was seen in the LAX airport with a missing wedding band, which only seems to add to the allegations. Sheremet and Rimes were married in 2002.
