Bieber has trust issues

Justin Bieber has struggled to make any new friends since shooting to fame as he can't bring himself to trust anyone outside of his "circle".

The Baby star reveals he has a small group of pals he has known since childhood, but does not let himself get close to anyone else.

He tells Access Hollywood, "I don't really let anyone in my circle. I don't really trust a lot of people, which is sad. But I kind of keep the people I grew up with close to me."
