The 45-year-old rock star is currently promoting his debut solo album 'As You Were' and his upcoming trip to the US will include an appearance on James' late-night show, even though Liam recently described the host as a "k***head".

The outspoken singer told BBC Radio 2: "We've got to go and do James Corden's show, that'll be awkward.

"I ain't singing in no car. I refuse to do it, I'm not doing it, mate. I'll sing the tunes, then I'm out of there."

Back in August, Liam insisted he won't appear on the popular 'Carpool Karaoke' segment of James' show, which has previously starred the likes of One Direction, Adele, Katy Perry and Ed Sheeran.

Asked whether there was any chance of it happening, Liam replied: "No thank you very much. No f***ing chance, mate. With that fat bloke from 'Kevin & Perry'?"

Then, Liam's partner, Debbie Gwyther, corrected the singer's attempt to reference James' popular British sitcom, telling him: "It's called 'Gavin & Stacey' and you've never watched it."

But Liam refused to back down, saying: "I don't need to watch it to know I won't like it. James Corden is a k***head."

Meanwhile, Liam recently confessed he's too "manic" to excel on chat shows.

The singer apologised on Twitter for behaving like a "sketchy little f***er" during an appearance on 'The Graham Norton Show', and he subsequently admitted he's simply not suited to the chat show format.

Liam said: "I've always found that side of things a bit odd. I think I come across too manic, I prefer to just come on and sing my song.

"But I had a bit of a chat. Graham's cool. He wasn't asking me stupid questions, I just can't handle that soap-y side of it."
