Leann Rimes and Eddies Cibrian's alleged affair has been 'outed' on a restaurant security camera, despite the couple's public denials.

The pair - who are both married - were forced to speak out after a U.S publication released a snap shot of the pair sucking face over dinner at Mosun and Club M in Laguna Beach.

Eddie said, "Other than being friends, and two actors who were romantically intertwined in a movie-for-television we filmed last fall, there is no truth to the reporting initiated by Us Magazine."

And Leann, sticking to their story, added, "There are rumours all the time. I let it roll of my back most of the time. It does get too much every once in a while but you know things pass, life happens."

But video footage of Leann and Eddie affectionately holding hands and kissing across the restaurant table appears to leave no doubt that their relationship is more than strictly platonic.

Meanwhile, Leann's husband Dean Sheremet wrote, "I love my wife!" on his Twitter page, confiming that he intends to stand by his woman.
