Justin is a cool guy, says David Hasselhoff

David Hasselhoff has confessed he had "a lot of fun" working with Justin Bieber and that he is a "cool" guy.

The 'Baywatch' star, who was on the set of the popstar's latest video, told People Magazine that people will hear more about their collaboration, but currently they are just keeping it quiet because it's really a cool video, and they had a blast.

Bieber had earlier confirmed the collaboration Sunday night on Twitter.
