"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**k, I need to aim this properly,' and I swung.
"You know in films when someone gets punched, and you hear that fake sound, like a slap? But in real life when someone gets punched, you hear that dull thud, a bit sickening?"
"I heard a sound like the last one, and saw his security guard looking at me like ... I'd cracked Justin Bieber right in the cheek with a golf club."
Sheeran, whose three latest songs are currently on top the ARIA charts, also spoke to The Guardian about how he's splashed his cash.
According to Forbes, he pocketed $A43 million last year alone.
"I did what any bloke would do - sorted my family out, bought a sports car that I never drive because I look like a tit in it, bought a house and built a pub in my garden," Sheeran said.
"I spoke to every dude I know and I was like, 'What would you do in the same position?' and they went 'Build a pub.'"
