Cowell envious of 'Dancing With The Stars'

Simon Cowell has admitted he is envious of producers of other successful reality shows.

The X Factor judge reveals he was enormously jealous when Dancing With The Stars became so successful, mainly because he missed an opportunity himself.

"If someone I know is doing better than me I get incredibly miserable," he said. "A lot of my friends are extremely wealthy, but I'm not envious of their money, however, I'm never pleased if they have a hit show. I don't go to bed thinking, 'I'm really happy their show is doing so well'. It annoys me that it wasn't my idea. When I watch Dancing with the Stars in America it makes me sick with envy because I didn't think of the idea myself."

He did add that he was comforted slightly by his emotions though, and said he would start to worry when he didn't feel envious of other producers: "That's how it should be - when you lose your competitive edge, you're over."
