There is nothing wrong with Justin Bieber: his manager

London: Singer Justin Bieber, who recently arrived late to a concert, collapsed on stage at another gig and then even had a fight with a photographer, is now doing fine. It was reported that Bieber's meltdown was because of his split from Selena Gomez in January after about two years of relationship.

Talking to E Online, Justin Bieber's manager Scooter Braun has revealed that the singer is fit and fine and there is nothing to be worried about him. "There is nothing wrong with him. He is in a great place. Justin is good, really good," E Online quotes Scooter as saying.

But a source said, "He simply hasn't been the same since he split from Selena. It really broke him. They were together for such a long time for two people so young. He hasn't quite known what to do without her." The source added, "He is lonely. They kept each other very grounded and understood the level of fame that they both had. Now his friends know he needs their support more than ever."

However, Justin Bieber's grandmother Kathy Bieber has defended him against accusations he has turned into a bad boy, but insists he should put on a free concert for his fans in Britain.
