On Wednesday, an unnamed insider told Page Six that a move (and a host swap) was being "talked about" – but this has now been contradicted by a different source.

“They are just exploring going to LA for a week with Colbert," the new source told the website.

Since March 2015, 38-year-old Corden, who was previously unknown in the US, has made a resounding success of his job as the host of CBS's The Late Late Show. His popular celebrity carpool karaoke segments, released via YouTube, regularly attract millions of views, while the show itself has performed well in terms of viewing figures and picked up multiple Emmy nominations.

Indeed, the most recent carpool video recently made headlines after Madonna confessed during it that she had once kissed Michael Jackson, after first "loosening him up" with a glass of Chardonnay.

Corden himself, too, is seen as a bit of a hot property and rising star: he was recently announced as the host for the 2017 Grammy Awards, replacing rapper LL Cool J (who has held the gig for the past five years).
