Mel Gibson has slammed reports he's divorcing his wife of 28 years after he was alleged to be cheating on her.

Recent tabloid reports suggested the actor was entangled in a $900 million divorce battle with wife Robyn Moore amid allegations of infidelity. Gibson, 52, sparked rumors of an affair after he was photographed with a 28-year-old Russian singer named Oksana in September. The gossip was further fueled when they were seen again together on the set of his new movie Edge of Darkness.

A source told the National Enquirer, "It may turn out that Mel's friendship with the woman is innocent, but Robyn warned him that if he embarrassed her one more time, their marriage is dead and buried." However a spokesperson for Gibson tells the New York Daily News the rumors of divorce and infidelity are "100 per cent untrue".

Gibson and Moore share seven children, aged nine to 28.
