When the "Love Yourself" buddies were in Japan, Sheeran admitted that things got a little out of hand after having one too many at a local 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," the British singer-songwriter explained to The Guardian. "I was like, ‘F--k, I need to aim this properly,’ and I swung. And 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. I’d cracked Justin Bieber right in the cheek with a golf club. That was one of those ‘What the f--k?’ moments.”
