The Shape Of You singer spoke out about his adventures while out of the spotlight during much of 2016. And though he spent time travelling and relaxing with family, he also made time for some boozy nights with friends – one of the being The Biebs.

And in a new interview, he tells how Canadian star Justin met the business end of his golf club after some drinks and bad decision making.

‘We were in Japan. We’d been out to a dive bar. He just drank water and I got hammered,’ he tells 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.’

Eh? Why a sober Bieber would suggest that is beyond us… Ed continues:

‘I was like, “F*ck, 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…

‘I’d cracked Justin Bieber right in the cheek with a golf club. That was one of those “What the f*ck?” moments.’

Aside from hitting fellow celebs, 26-year-old Ed also spoke about his hopes for his upcoming album, ÷ – and it’s clear we’re in for a treat, as he’s confident about its contents.

When asked how he’d feel if the album sells fewer copies than 2014’s x, he responds:

‘I’ll bet you anything now it won’t. I don’t think there’s any possibility it will. The next album, I promise you, will sell less, but this album will sell more. I don’t think I’ll have a year like this again.’

We can’t wait to see whether his prophecy comes true…
