Justin Bieber put 'everything' into relationship

The 'Boyfriend' hitmaker called it off for good with the 'The Heart Wants What It Wants' singer in October last year following an on/off relationship and now admits he tried to be too serious too quickly.

He explained: "I think so. I think with that relationship ... I put so much of myself on the line with her, because I was so distant with everyone else. So it's like, you have the world who's loving you but it's not like they know my heart - they don't know me.

"So when I found that love I was just like, 'Woah, I want to hold on to this'. And I just put everything into it and in reality there's just no holding back. You're just like, 'This love feels so good.'"

And whilst the 21-year-old singer insists their relationship was "magical", he found it hard to deal with people "judging" him about something so personal.

He added to i-D magazine: "It's like, magical. There's nothing like it. So I felt that and I just didn't want to let it go. When it was hard, I was just like, 'I want to stick this out.'

"We were working out how to be in a relationship, how to be ourselves, who we were, in the middle of having people judge our relationship through the media. I think that really messed my head up too.

"Because then, it's like trust and all this other stuff that starts messing with your mind. You're on the road. And there are beautiful women on the road. And you're just getting yourself into trouble."
