The Chains singer said that he thinks being naturally groomed is “the beautiful part about being a man”.
He told Attitude that he was surprised by the reaction to some of his recent photoshoots, which have seen him show off chest and back hair.
He said: “It’s funny, I never even really thought about it; that that would be an issue. I think that I’ve never even tried to like wax or shave my chest hair or anywhere else.
“I just think, ‘I’m a man, I don’t really need to!’ That’s the beautiful part about being a man! It’s a whole lot of trouble to do all that!
“But actually when we were doing some of the Kingdom shoots in our fight-wear – which is just shorts and that’s it – one of my friends on set who’s this awesome lesbian chick was like, ‘You know what I really dig? I really dig that you don’t shave or wax – keep that up!’ And I was like, okay, if that’s coming from her then I’m all good to go.”
The 22-year-old has undergone a physical transformation in preparation for his appearance on Kingdom, which sees him play a martial arts fighter.
He explained: “I changed my diet quite a bit. Lean protein and vegetables, the very boring side of things! I worked with a trainer and basically pushed myself to the limit; two workouts a day and just really going there with it – and the fight training on top which was pretty insane.
“I’d never done any mixed martial arts before but it’s a whole lifestyle, it’s not just a sport. You really have to commit to it.”
