"I have a contract for this year and that is it," he said. Simon, 50, dropped his bombshell as he confessed the launch of US X Factor could leave him no time to do the UK programmes. He said he still had not decided if the UK's X Factor could go ahead without him as a judge however, said it would have to switch dates.
Simon is due to start US X Factor in September next year just as the UK show would be getting into full swing. "It will have to move. Do people want it back? I am going to sit it out for a few more weeks before I make a final decision. And it has to be fun. The minute it stops being fun, bye bye," he added.
