Simon Cowell: Jealousy is healthy
Simon Cowell has admitted he has a jealous streak - but says it's good for business.
The TV and music mogul, who has become a dad with Lauren Silverman, spoke about the personality trait in a chat with hypnotist friend Paul McKenna.
"I think jealousy in a weird way is good for you. In a relationship it means that you care," he said.
"You shouldn't get too jealous," he said, before adding: "If you are not jealous of your competitors you are not going to win."
The Sun quoted the star - whose X Factor show has recently taken a knock from Strictly Come Dancing in the ratings - as saying: "When I see a competing show doing well, I feel physically sick. I don't like my friends to do well."
Simon spoke to Paul for the hypnotist's new online show, McKenna.
He said of being a judge on Britain's Got Talent and The X Factor: "Auditions for me are like going back to school - and the only way I got through school was being really badly behaved."
