Oh, if we could have been a fly on the wall when this happened!

Ed Sheeran has admitted to accidentally hitting Justin Bieber on the face with the golf club.

Speaking to The Guardian, Ed said that they were in Japan at the time, and he got "hammered" in a dive bar. The lads then went to a golf course where the incident happened.

"We were in Japan. We'd been out to a dive bar. He just drank water and I got hammered.

"Then we went to a golf course, and he lay on the floor and put a golf ball in his mouth and told me to hit it out of his mouth. I was like, 'f*ck, I need to aim this properly,' and I swung.

"I'd cracked Justin Bieber right in the cheek with a golf club. That was one of those 'what the f*ck' moments."

What a night out that must have been.
