He's no stranger to facial injuries of his own, given that scar he received from a sword-wielding Princess Beatrice at a party - but Ed Sheeran is capable of inflicting them, too.
Better still - if you can't stand Justin Bieber, you'll enjoy this one.
In an interview with The Guardian, Sheeran told a story about when he was in Japan - possibly while travelling on his year off last year - and drinking in a bar with Bieber.
"We’d been out to a dive bar. He just drank water and I got hammered,” he said. “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, ‘Fuck, 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?
