Jimmy Kimmel accuses James Corden of LYING about Britney

As Carpool Karaoke segments go, Britney Spears' appearance on the uber-popular Late Late Show segment was underwhelming to say the least.

Maybe the bar had been set too high with past Carpoolers or maybe our inner teenyboppers just really wanted Britney to smash it, but for some reason, it just didn't, well, work.

And James Corden, who did his best to get Brit to chill out and loosen up, faced a grilling from fellow chatshow host Jimmy Kimmel this week when the guys sat down to the show’s Spill Your Guts or Fill Your Guts segment.

Going in for the kill, Jimmy asked: ”Were you as miserable doing Carpool Karaoke with Britney Spears as it looked like you were?”

Looking genuinely taken aback by the accusation, James replied: “I’m very sad it looked like that. I wasn’t, I wasn’t miserable at all. “

“It… it was great! I wasn’t, I genuinely wasn’t. I think she’s great. I do,” the British star added while trying to contain his nervous laughter.

But Jimmy wasn’t having it, and he made no secret of it either.

Skip to 3.00 for that magic moment.
