George Clooney has laughed off Roseanne Barr's outrageous claims they once got so drunk together he allowed her to keep a photograph of his genitals, insisting she has twisted the truth.

The comedienne recently alleged that Clooney, who found fame as Booker Brooks on her sitcom ROSEANNE, posed for the saucy picture during a raucous drinking session, and allowed her to display the image in her kitchen.

She said, "We were all drunk, John Goodman took a picture of George naked with Groucho Marx glasses over his private area and we used to have that on the fridge."

However, while the Oscar-nominee admits the tale is partly true, he insists Barr played no part in his puerile prank.

He tells the New York Daily News, "I called it The Face. But I knew better than to do it at that stage of my career. I must have told her the story."
