The former American Idol judge is apparently moving on... again!

Simon Cowell and Cheryl Cole informed ITV chief Peter Fincham that they are quitting the UK X Factor to focus on the new American version, according to News of the World.

"I'm committed to the American show and I'm not going to do both," Cowell allegedly told ITV. Rumored to take over for the pair? Robbie Williams and Adele.

Here's Cowell with fiancee Mezhgan Hussainy at dinner in London last night - looks like the famous Brit has a lot on his mind!

The new X Factor is scheduled to premiere in September 2011.
