Just because Eddie Cibrian cheated (at least) once doesn't mean he'll do it again. Well, that's his story and he's sticking to it, as a tabloid reports that he's cheating on his girlfriend, LeAnn Rimes. Star magazine reports that the recently canned CSI: Miami actor is getting a little action on the side from none other than his soon-to-be ex-wife, Brandi Glanville. The tabloid reports that Eddie was visiting his children and put them to bed with Brandi, then the two had sex in the hallway and again in the living room a few weeks later. LeAnn found out and naturally freaked out, but the tab says Brandi doesn't have designs on getting her husband back - she simply wanted revenge. Cibrian protested the claims, saying, "Once again my ex has stooped to a new low attempting to sabotage my beautiful relationship with LeAnn," the former CSI: Miami actor writes. "Not surprisingly the ONLY magazine that decided to run the story shares the same credibility and delusion as my ex. They should be ashamed of themselves." We think maybe he should save his outrage for after the divorce papers are signed. LeAnn's divorce from Dean Sheremet became final late last year; Cibrian's from Glanville isn't finalized yet.
