His return has seen viewers commenting on how much the singer has changed since he was a 14-year-old child star - most notably he’s now sporting augmented lips.
‘I think it’s best to do whatever makes you feel good,’ he says. ‘That’s the thing with me over the years I’ve been looking for my identity.
‘I’ve been trying to find myself again and I’ve definitely experimented with filler and whatever, and there’s no denying that. I think it’s pretty obvious.
‘[Laughs] I’m so used to seeing those articles, because to me it’s not a big deal. To me, lip filler is like makeup, it’s like doing your hair ... It’s not permanent.
‘I’ve never had any kind of plastic surgery or anything like that. I think it’s each to their own, whatever makes you happy. It’s such a small thing for me.’
