One Direction are set to appear on The Late Late Show with James Corden next week, which will mark their first televised interview as a four-piece following Zayn's exit.
Speaking to reporters at the TV BAFTAs this week, James said: "No one can replace Zayn, it's about the four of them and they have a very rich and brilliant future ahead of them."
James also revealed that he will be filming a funny "skit" with the boys when they join him on his US chat show.
Harry Styles, Liam Payne, Niall Horan and Louis Tomlinson have already teased "a few surprises" ahead of their appearance.
Last month, Zayn quit 1D after five years in the band. He said in a statement that he had to do what felt right, and expressed his desire to be a "normal 22-year-old".
1D have continued as a band and are currently working on a new album, but last week, Zayn's exit was brought up once again after he clashed with Louis on Twitter.
