The singer, who came second in the 2007 series, told the News of the World that Simon Cowell is the only important judge.
"She's not a great singer and being a judge isn't the hardest job in the world," he said. "You sit there and tell people when a note is flat. Cheryl's eye candy. Simon's the only judge people care about. "
He joked: "I'd do it for what they get paid."
