• Ashton Kutcher shared an old story about Harry Styles
  • He didn't know who Harry was at a karaoke party
  • Kutcher basically gave Styles singing advice

Ashton Kutcher just confessed to one embarrassing story involving himself and Harry Styles. The actor says it all left him feeling like "a jerk."

It goes like this. Ashton Kutcher and Mila Kunis were attending a star-studded karaoke party in the neighbourhood.

A young Harry Styles took the stage for karaoke and, as you might expect, blew everyone away.

The only problem? Ashton Kutcher didn't know who Harry Styles was. And it got a little awkward later... when he basically gave Styles advice about his singing.

Kutcher explained to Esquire that he went up to Styles and said: "Man, I gotta tell you something. You're really good, like really good."

Kutcher recalled Styles thanking him and saying: "I really appreciate that." (So he likely realized what was happening!)

But not long after, Kutcher clued into who the mystery karaoke singer was. Another friend soon told him: "It's Harry Styles."

Kutcher even took the opportunity in the Esquire interview to offer a tongue-in-cheek apology: "I just really want to say, I'm sorry Harry Styles, but you're really good at karaoke man. Seriously, like really good."
