Country star Rimes, beau deny infidelity rumors

Country-music star LeAnn Rimes and former "CSI: Miami" actor Eddie Cibrian are denying a story in Star magazine that claims Cibrian has been cheating on Rimes with his ex-wife Brandi Glanville, the mother of his sons Mason 7, and Jake, 3.

The denials come from their unverified Twitter accounts during a camping trip they say they're on. Rimes' account posted a photo of Rimes and Cibrian smooching, captioned "Kisses!!"

Cibrian's tweets were a bit more confrontational. Linking to the site Twitlonger.com, he seethed for over 140 characters, "Once again my ex has stooped to a new low attempting to sabotage my beautiful relationship with LeAnn. 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."
