The 'Boyfriend' star says he also feels grown up in the music industry and doesn't trust anyone.

Justin Bieber has defended Kim Kardashian in a new interview with GQ magazine.

The 'Boyfriend' star stood up for the reality star amid claims that she has not earned her celebrity status.

"People say she doesn't do anything, she actually does do stuff. She works hard," she said.

The interview sees the 18-year-old singer pose in a blue suit jacket with his new quiff-styled haircut.

Justin also stressed that despite only being 18 he still felt grown up within the industry, and was always careful about who he trusted.

"I mean, I keep my guard up a lot, because you know, you can't trust anyone in this business," he said. "That's what's sad. You can't trust anybody. I learned the hard way."

Justin is currently preparing for the release of his new album 'Believe', which comes out in June. The record features collaborations with the likes of Kanye West, Drake and Taylor Swift.
