celebrity

James Corden just named and shamed the 'rudest' celebrity he's ever met.

Hollywood A-listers aren’t exactly known for their good manners, but there’s one star who left James Corden with a particularly bad taste in his mouth.

Literally. The Late Late Show host almost drank a whole glass of bird saliva to avoid outing this guy.

During the “Spill Your Guts or Fill Your Guts” segment — in which you either divulge secrets or indulge in some truly disgusting foods (think cod sperm) — Corden faced off against his guest Khloe Kardashian.

The Keeping Up With The Kardashians star asked if any celebrity had ever been rude to him at a party.

As is it turned out, one man had in fact left Corden a tad shaken (and stirred) at a U2 concert: Pierce Brosnan.

Surprised?

Corden and his wife Julia Carey were enjoying the dulcet tones of, um, Bono, when the confrontation (slight bump?) occurred.

“So me and my wife moved into this area and, literally, I’ve never felt anything like it, this arm went on here and just pushed me out the way. And I looked at him, and he didn’t even glance at me and he just moved back into his area," he said.

“Maybe he was drunk?” the reality star suggested.

“Maybe he’s just a bit f**king rude," the host hit back.

Looks like James Bond won't be appearing on Carpool Karaoke anytime soon...

Yikes.
