Canadian pop star Justin Bieber has opened up about his relationship with American actress and singer Selena Gomez. The Baby hitmaker has revealed that he and the former Disney star used to have serious fights while they were dating.

"I moved in with my girlfriend when I was 18. Started my own life with her. It was a marriage kind of thing. Living with a girl, it was just too much at that age. But we were so in love. Nothing else mattered. We were all about each other," he said in an interview with Complex.

"But when it's like that and you get your value from that, people will always disappoint you. Your girl or your dude, they're always going to disappoint you. Your full identity can't be in that person. My identity was in her. Her identity was in me. When stuff would happen, I would lose my freakin' mind, and she would lose her mind, and we would fight so hard because we were so invested in each other," he added.

It was previously reported that Gomez is ready to rekindle her romance with Bieber, if he is ready to cut off from his female friends. In an interview with Elle, the 22-year-old Come And Get It singer talked about her relationship with the Boyfriend singer.

"I'll forever support him and love him in a way that.... We grew up together. I think people want it to be different," she said. "We're too young for that. Nobody was married. There was no.... I respect him. And I think he respects me, in a healthy manner."
