Justin Bieber is worried he will "damage" rumoured girlfriend Hailey Baldwin and doesn't want to "rush into" anything with the model.
The 'Sorry' singer still hasn't confirmed his relationship with the 19-year-old model and he admits he is hesitant to "rush into anything" with her incase he "hurts" her in a way they can't go back from.
He said: "What if Hailey ends up being the girl I'm gonna marry, right? If I rush into anything, if I damage her, then it's always gonna be damaged. It's really hard to fix wounds like that. It's so hard.... I just don't want to hurt her.
"I know that in the past I've hurt people and said things that I didn't mean to make them happy in the moment. So now I'm just more so looking at the future, making sure I'm not damaging them."
And Justin - who previously had an on/off romance with Selena Gomez - admits he worries about taking on the "responsibility" of a relationship.
He told America's GQ magazine: "I don't want to put anyone in a position where they feel like I'm only theirs, only to be hurt in the end. Right now in my life, I don't want to be held down by anything.
"I already have a lot that I have to commit to. A lot of responsibilities. I don't want to feel like the girl I love is an added responsibility."
Though the 21-year-old star is no longer dating Selena, they are always there for one another.
He said: "We don't talk often, but we're cordial. If she needs something, I'm there for her. If I need something, she's there for me."
Elsewhere in the interview, the 'What Do You Mean?' hitmaker revealed he had been taking ADHD treatment Adderall "for about a year" but has now given up the medication because he was suffering from anxiety.
He said: "I've been getting a lot of anxiety, and they think it's stemming from the Adderall.
"That's why I've stopped taking it. Or else I wouldn't stop, because I really enjoy it."
Justin Bieber really 'loves' Hailey Baldwin
Justin Bieber has gushes about model Hailey Baldwin, saying "she's someone I really love."
The 21-year-old singer has been romantically linked to the 19-year-old model and while the pair have never confirmed a romance, Justin couldn't help gushing over her in a recent interview.
He told American GQ magazine: "She's someone I really love. We spend a lot of time together."
Justin also admitted he has done some "dumb s**t in his past, including wild partying, arrests for driving offences and egging a neighbour's house, but insisted that his song 'Sorry' was about an ex-girlfriend and not an apology for his outrageous antics.
He said: "Everyone when they start growing up realises, 'Man, I did some dumb s**t when I was younger.' It's not just me . . . If I could go back I wouldn't really change much. I think it's all my journey. That stuff made me who I am.
"People ran with that... that I was like, apologising with that song and stuff. It really had nothing to do with that . . . It was about a girl."
Justin previously revealed he cut out the bad influences in his life once he decided he wanted to change his ways.
He said: "I just had to figure out what kind of man I wanted to be. I have awesome people in my corner.
"I'm human I'm still going to make mistakes. I think that's what's cool about this growth is people can see it. I've made a transition and been consistent."
