"When I got the CNN job I banned her from the show, permanently. She responded by saying she'd never heard of me, but we both know she's lying."

He said: "Gwyneth is a dark horse, much more fun than you might think.
"When I asked her about her reputation, she told me she was a demure, lovely, sweet, innocent little lady ... except in the bedroom.
"I had a good laugh with Cameron at Vanity Fair [Oscars party]. She's a really cool girl, good fun. She wants to come on my show, but only when she's got something intelligent to say."
