Frank Skinner has unleashed on Simon Cowell saying the star's face looks like a Slipknot mask.
Simon, 59, unveiled a dramatic physical transformation recently after dropping 20lbs on a vegan diet but comedian Frank, 62, is not impressed by his altered appearance.
Speaking to Dave Berry on his Absolute Radio Breakfast Show, he went on a lengthy rant full of insults, beginning with: "I remember Simon Cowell when he had his first face. I've known him a long time.
"The current one is a bit Slipknot. It's actually quite terrifying. It looks like his nose is juggling his eyes. They are at different levels. A man of his money you'd think could get the best plastic surgeon in the world.
"I think it's to do with the power cuts we had recently, I think it was done in darkness. It really is shocking.
