Usher thinks Justin Bieber is better with relationships than he is.

The 'OMG' hitmaker - who is currently locked in a bitter custody battle with estranged wife Tameka Foster over their sons four-year-old Usher Raymond V, and Naviyd Ely Raymond, three - admires the teenage singing sensation for the way he ''understands'' being in a committed relationship.

Speaking about Justin, 18, who is dating Selena Gomez, he said: ''Check it out, in the area of relationships, Justin has actually done a lot better than I did. He doesn't have as many issues. He knows what he wants. What were my issues? Well, maybe me not locking into one relationship. I was a little bit more experimental.

''I've had many women and I understand how to deal with a lot of different ones.

''He understands, this is a woman I'm choosing to deal with and these are the women that are there. But it is complicated, when your reality is a fantasy. Fame is the modern double-edged sword.''

Usher, 33, is pleased to be Justin's mentor and believes ''God did a great thing'' allowing them to meet.

He told Q magazine: ''God did a great thing placing us in each other's lives. Because there is a world of experience only I can share with him.''
