(Cover) - EN Showbiz - Justin Bieber has never experienced heartbreak.

The 18-year-old singer is happily dating Selena Gomez and has never had a romance which has gone sour. This means that he disagrees with Black Eyed Peas star will.i.am, who says all singers need to have been through hard relationships to sing about love.

"I haven't gone through it, so I don't really know what it's about. I don't think anyone wants to have heartbreak. I haven't been in that deep a place yet, but I'm still looking. I'm still learning every day," he told Seventeen magazine.

Justin enjoys his job but it has impacted some areas of his life. He finds it hard to trust people, so he hasn't made many new friends since hitting the big time.

"I don't let anybody close to me. I just rock with my old friends, Ryan and Chaz. I'm happy with the friends I have," he has explained. (C) Cover Media
