The 27-year-old country songbird's divorce was finalized on Friday, six months after she and Sheremet, 29, reached a settlement and about a year since her torrid on-set affair with Cibrian doomed her marriage to her former backup dancer.
However, while Cibrian and his estranged wife, Brandi Glanville, had been close to ending their own marriage, his recent unemployment situation has thrown a monkeywrench in their settlement plans.
Cibrian was dumped from CSI: Miami after producers declined to pick up his contract.
"He blames bad press from his ex for losing his job," a source close to the couple tells E! News. "Now they are at ground zero with negotiations. He is trying to pay her nothing."
Glanville is now worried about keeping up her lifestyle in the wake of his loss of income.
On the bright side, Cibrian can always mooch off Rimes, whom he stuck close to during a weekend performance in Orange County.
He had no immediate comment on his looming divorce, but Rimes was far from reticent.
"It makes me sad that the media once again can take something as personal as a divorce and make it a top news story. It's hard enough dealing with it on our own. Sucks to see it in your face at all times," she tweeted on Sunday.
"Well, maybe now we can move on. Thx to all my friends and fans for their unwavering support of both Deane and me. We've both needed it! Your love means a lot."
It goes without saying that LeAnn Rimes and Eddie Cibrian have landed a plum spot in our Big Celebrity Splits gallery.
