James Corden talked "a lot" to Piers Morgan in his deliberations about becoming host on one of America's most popular chat shows.
The Gavin And Stacey actor is currently enjoying success across the pond presenting the Late Late Show on US network CBS.
But before he took the job he got advice from Morgan whose US show Piers Morgan Live was cancelled following plummeting ratings.
In an interview with The Sunday Times Style magazine, he said: "I actually talked to Piers (Morgan)] quite a lot in my deliberations about taking the job.
"He was the person saying, 'You've just got to go for it. It's really hard and the critics will absolutely go for you, but if you just bed in and carry on, you'll be fine'.
"Luckily, that mauling didn't really happen, but it was useful to have someone who had been through that sort of thing before."
Corden, who was relatively unknown in America, made his chat show hosting debut in March this year.
He took over from Scottish-born Craig Ferguson and moved to Los Angeles with his family to make the show.
