James Corden could be offered a primetime slot after impressing with The Late Late Show.
CBS bosses are reportedly so determined to prevent the 37-year-old star from being poached by a rival network, that they are considering moving him to a primetime variety show.
A source told the Mail on Sunday: "James has become one of the most wanted men in Hollywood. He has been getting all sorts of offers and CBS doesn't want to risk losing him.
"The plan is for a primetime variety show which showcases all his talents. The move will happen sooner rather than later. The talks started last week."
While CBS have not commented on the claims, CBS Studios International president Armando Nunez recently spoke of his admiration for James.
He said: "In just over a year, James has made a very big mark on US late night television with a critically acclaimed show that features the biggest names in entertainment, and unique segments that quickly become digital sensations."
James previously revealed that he has been offered a recording contract after impressing music bosses with his segment Carpool Karaoke, which has seen him show off his vocal abilities alongside the likes of Adele, Justin Bieber, Stevie Wonder and One Direction.
The comic revealed: "I've had a couple of record deal offers from both England and America."
The British star has been living in Los Angeles since agreeing to take over the reins of the CBS series from departing host Craig Ferguson.
But James - who once dreamed of being in a boyband - says he has no plans to take up the offer.
He said: "No one has to worry - I'm not going to embark on such a thing!"
