Spice Girls singer Mel B has labelled James Corden as one of the 'biggest d***heads in showbiz.
Appearing on The Big Narstie Show, Mel, 47, was asked to come up with a list and also said Geri falls under that category.
The Spice Up your life singer tells comedian Mo Gilligan that the older she gets, the less tolerance she has for annoying people.
Narstie asked Mel why she doesn't like Late Late show host James Corden.
She said: “I think you always have to be nice to the people that you work with whether it be production, camera guys, sound, lighting - we all work for the same thing. So you should always be nice and he hasn’t been very nice."
Corden, 44, was widely criticised in October after he was banned from New York eatery Balthazar amid claims he had been "nasty" to waiting staff.
The Gavin and Stacey writer was called a "gifted comedian" but a "cretin of a man" in a furious Instagram post, shared by owner and food mogul Keith McNally. Corden apologised for the matter and his ban was lifted.
The TV personality then further said he's done "nothing wrong", sparking another outburst from Keith on social media.
Mel, who appears alongside actor and presenter Jordan Stephens, comedian Nabil Abdulrashid, Billy Billingham from SAS: Who Dares Wins and social media star Alhan Gencay, insisted that she 'loves' Geri to pieces, but at times she can be 'f***king annoying'.
When Mo asks Mel who she thinks is the biggest d***head celebrity she's ever met, she lists off a couple of surprise answers, including Geri.
Mel B: “So, there’s a few. James Corden, Geri Halliwell, Jessie J and me. I know, I love Geri to bits but she’s really f***ing annoying.”
Mel's sassy appearance on The Big Narstie show comes after she walked off an interview on The One Show earlier than expected.
Viewers of The One Show took to social media to slam the episode, hailing it a 'car crash', while calling out host Alex Jones for 'losing control'.
The episode, which was aired on Thursday 24th November, featured an interview with Emily Atack, Mel B and Ruby Wax, who were all on the show to promote their new TV series, Trailblazers: A Rocky Mountain Road Trip.
However, chaos ensued as Mel B and Ruby Wax rolled around on the sofa in hysterics. Viewers were also left feeling angry with the guests for speaking over each other.
As was Mel B, who eventually became so frustrated when the other stars continued to speak over her, that she got up to walk out of the interview.
It was when Ruby made a comment about the show, saying: "We were after the American dream and then it went rotten”, to which Mel replied: "Just like this interview. Don't forget to tune in guys on Monday."
She then got up to leave, before she was made it sit back down by her co-stars.
The Big Narstie Show airs on Friday 2nd Dec at 11:05pm.
