Pop star Justin Bieber has a crippling fear of flying.

The teen sensation is convinced he risks his life every time he steps onto a plane, but he has ruled out purchasing a private jet because chartering it would become a "bad habit".

He tells British magazine Live, "I just started to really not like getting on a flight. It scares me. When I get anxiety, my heart drops and starts beating really fast as if it's going to explode...

"People say you have more chance of getting into a car accident than a plane crash, but they do maybe one flight a year and I'm on planes all the time. And all the time I'm thinking I have no control. If this plane crashed I'm dead. I feel like every time I get on a plane I'm risking my life."
