James Corden thinks Zayn Malik is irreplaceable in One Direction.
The 'The Late Late Show...' host thinks 1D are right to continue as a four-piece in the wake of Zayn's departure from the boy band as it wouldn't be right to add a new fifth member.
But Corden firmly believes the pop group have a "rich" future together as a foursome.
Talking on the red carpet at the British Television Academy Awards at London's Theatre Royal, the 36-year-old TV personality 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."
The former 'Gavin & Stacey' star is going to be the first person to interview all of One Direction - Harry Styles, Louis Tomlinson, Liam Payne and Niall Horan - since Zayn left in March.
When asked if he was nervous about the interview on his US talk show, he said: "I'm not nervous, I saw them on Friday ... And I'm seeing them tomorrow, we're filming a skit so it's all good."
On whether he was looking forward to speaking with the 'Steal My Girl' hitmakers, he told ITN: "It's going to be great. I consider them friends, so I just hope we make a fun hour of TV."
Corden jetted in from US especially for the BAFTAs on Sunday (10.05.15) and flew back this morning (11.05.15).
Talking to the BBC, he said: "I'm on the aeroplane longer than I am in London."
One Direction will be on 'The Late Late Show with James Corden' on 14 May.
