Despite being the world's two biggest male pop stars, good pals Ed Sheeran and Justin Bieber still know how to have a proper lad's night, filled with questionable decisions and alcohol-induced injuries. 

In a new interview with The Guardian, Sheeran shared an anecdote from one particularly spirited night out with the Biebs. On this particular occasion, it turns out that Sheeran was the only one who was "hammered," while Bieber, now sober after his savage teenage years, drank water all night. But it was Biebs who put himself in danger by making his own face the platform for a risky stunt, to be performed by his highly impaired British crony. 

“We were in Japan. We’d been out to a dive bar. He just drank water and I got hammered," Sheeran told The Guardian. "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." 

Safe to say, Sheeran didn't execute a clean drive down the fairway. 

"And you know in films when someone gets punched," he continued, "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?" Yikes... 

"I heard a sound like the last one," Sheeran confessed, "and saw his security guard looking at me like [mimics a horrified expression]. “I’d cracked Justin Bieber right in the cheek with a golf club," he said of the inevitable result of his drunken golf stroke. "That was one of those ‘What the fuck?’ moments.”

Sheeran's brand new album, ÷ [Divide], can be streamed here. No sign of new music for Bieber, but luckily, his mug seems to have recovered from the blow it took from Sheeran's driver.
