Bieber 'doesn't have many mates'

You'd think a global superstar like Justin Bieber would have tonnes of mates, right? Wrong.

"I really don't have a lot of friends," the singer's revealed. "I have like three close friends that I'll fly out to see me or I chat with or call. But, I mean, that's really the truth."

He was talking to American talk show host Oprah Winfrey in a special one-to-one interview.

Bieber also said he gets lonely sometimes.

"I get days where like I am just down and, you know, gloomy... Just because I'm human."
