LeAnn Rimes and husband Dean Sheremet leaving a medical building in Bevelry Hills. Los Angeles, California - 19.02.09

One of Dean Sheremet's cousins, calling herself Pebbles, called in to Michigan's Mojo In The Morning radio show on Friday (20Mar09) to comment on reports suggesting Rimes has been cheating on her husband with married actor Eddie Cibrian.

And the relative revealed the family is far from shocked by leaked security video footage, which appears to show Rimes and Cibrian getting intimate and kissing at a restaurant on a secret date - they're surprised the marriage has lasted so long.

Pebbles told the morning show, "There were so many situations that happened when we were teenagers... He's gay. He's been gay since he was probably five.

"The family literally used to take bets on what age he would come out, and then all of the sudden he got married!"

Both Rimes and Cibrian's publicists have dismissed the reports of infidelity, and, in his only comment about the media fuss, Sheremet, who renewed his wedding vows with Rimes last August (08), posted, "I love my wife!!!" on Twitter.com.
