LeAnn Rimes has been carrying on a thinly veiled affair with her Lifetime TV-movie co-star Eddie Cibrian. Denials all around…except from Eddie’s wife Brandi Ganville, who has just tossed him out. Brandi says LeAnn and Eddie deserve each other. Deny all you want; Snarkista calls ‘em like she sees ‘em…and she’s been watching this one for months.

LeAnn’s married too, you know. She’s been hitched for 7 years to that super-pretty Dean Sheremet who used to be a backup dancer…and looks like he’s still probably GREAT at ballet.

LeAnn’s house isn’t too far from Snarkista’s, but it sure is bigger! It’s just hit the market for a cool $7.5 million, which buys you a lot of real estate in the Nashville area. Her peeps say the sale has nothing to do with any affairs or cheating or anything. It’s about spending more time in Hell-A. LeAnn has bounced back and forth from Nashvegas and the West Coast for awhile. Just don’t expect to get as many square feet in the City of Angels, LeAnn. No matter HOW sucky the California real-estate market is.

“This is a difficult time for me and my loved ones, but I appreciate all your continued support,” she wrote today. “I would like to assure all of you that this is a place for you to hear things directly from me and as you all know, not everything in our lives is always black and white.”

LeAnn ends by telling fans to “have faith.” Faith that she’ll dish the scoop first on her website?! Somehow that little diary doesn’t sound so great for hubby Dean.

Rimes, 26, is married to Dean Sheremet, who is a former backup dancer. US magazine writes that Rimes “got cozy with [Eddie] Cibrian, 35, on the set of her March 21 Lifetime flick, Northern Lights.” Cibrian is married to model Brandi Glanville, and they have two sons.
