Simon Cowell is planning to move back to America. The music mogul is said to be 'open' to returning to Los Angeles with homesick girlfriend Lauren Silverman and their nine-month-old son Eric. He plans to relaunch 'The X Factor' in the US.

A source said: "Lauren regularly flies to and from the US and UK and she has admitted to Simon she's still homesick for America and wants to move back. She says she's struggled to make new friends and misses her old life.

She wants them to move back to LA once X Factor is finished. Simon is open to the idea. He's frustrated at how X Factor has fared in the UK ratings this year and is contemplating trying to re-launch the show in the US"

Insiders claim Simon, 55, plans to rework the talent show in a bid to revive it Stateside and boost his own profile.

The source added to Closer magazine: "Simon's keen for a new concept for the American version. It will be much more about bands and older acts rather than younger novelty singers.

Lauren supports him and would love to be based in the US with him. He's already in informal talks to make a pilot of the show in the States, to get the whole idea up and running. He wants to blow America away and get back his crown as the King of Entertainment. Lauren thinks Eric can still have the best of both worlds if they have a main base in LA and pop back to London when they need to."
