The 55-year-old music mogul - who is currently head judge on 'The X Factor' - has reportedly been signed up to take over from the comedian and talk show host on the next series of the US talent show following his decision to quit earlier this year.

A source shared: "Simon has been off the television in the last couple of years focusing on family life. But with his comeback to British screens, he also wants to make his way back into America.

"And he's more than used to the travel."

Simon - who is also a judge on 'Britain's Got Talent' - first appeared on US television on 'American Idol' from 2002 to 2010 before launching the US 'X Factor' in 2011.

However after the show failed to take off in the States, the Syco boss decided to return to the UK version last year.

And if Simon does join 'America's Got Talent' he will be reunited with his former fellow 'X Factor' judge Mel B - who was axed in favour of Rita Ora earlier this year - who sits on the judging panel alongside Heidi Klum, Howie Mandel and the departing Howard Stern.
