“The Late Late Show” host James Corden is admitting to “rude” behavior a week after New York restauranteur Keith McNally temporarily banned him from Balthazar.

McNally said Corden apologized and ended the ban, but Corden finally spoke publicly about the controversy on Monday night, saying he got upset because his wife received food she was allergic to.

“As her meal came wrong to the table the third time, in the heat of the moment, I made a sarcastic, rude comment about cooking it myself,” Corden said.

“And it is a comment I deeply regret. I understand the difficulties of being a server… I worked shifts at restaurants for years. I have such respect and I value anyone that does such a job — and the team at that restaurant are so great, that’s why I love it there. The restaurant manager and the server there were lovely, they brought out four glasses of champagne as an apology, but we were like, ‘That’s not necessary, we don’t need it.’”

Corden said he initially thought he didn’t need to apologize, but acknowledged he made a “rude comment” and settled the matter privately with McNally.
