Teen sensation Justin Bieber has admitted that although he couldn't take One Direction in a fight as a group he could definitely hold his own with the individual members.

The 'Boyfriend' sensation enjoys watching boxing and recently had a sparring session with former world heavyweight champion Mike Tyson, and is quoted as saying that he could knock out the five boyband heartthrobs in separate one-on-one scenarios without too much trouble:

"I'd get my ass kicked (against all of them). But one-on-one I'd take them. I'd try a spin-kick. To the face."

Bieber sent out a tweet yesterday (July 4) and wished his American fans a happy Independence Day, joking: "Happy 4th to all you americans letting us canadians bbq with you today. Have fun."

Earlier this week, Bieber confirmed that his highly anticipated 'Believe' tour will span the globe.
