James Corden regrets kissing Sean Spicer at the Emmy Awards on Sunday (17.09.17)

Addressing the incident on 'The Late Late Show' on Monday (18.09.17), James explained: "The big winners last night were Donald Glover, Hulu and former White House press secretary Sean Spicer. Spicer won best actor in a comedy for his role in Donald Trump's administration.

"I'm kidding, of course. But Sean Spicer actually did make a cameo at last night's ceremony.

"According to some reports, at the after-party, Spicer was the most popular guy in the room. And I just want to say, I think people are forgetting that this man lied to the American people, and should not be embraced."

At that point, a photograph of James landing a kiss on Spicer's cheek appeared on the screen.

The 39-year-old star quipped: "These Hollywood phonies kissing up to Sean Spicer are disgusting. I mean, who did this? Who are we talking about here?

"Yeah. I know you think that is a picture of me kissing Sean Spicer.

But in the spirit of Sean Spicer - no, it isn't.

"Anyone ever have that feeling when you get a little drunk and then wake up the next morning and think 'Oh God, who did I kiss last night?' It's a bit like that."

James then seemed to adopt a much more serious tone, adding:

"Understandably, some people have been disappointed by this photo. In truth, I'm disappointed by it as well.

"I am. I have been reading a lot of harsh comments on Twitter today, and I hear you loud and clear, truly, I do."
