David Hasselhoff believes he has been nicknamed "out of respect".

The American actor-and-singer has amassed an impressive fan base since starring in popular TV shows Baywatch and Knight Rider. David has acquired a moniker since being in the public eye, and the star thinks this is testament to his notable reputation.

"Ninety nine per cent of people now call me The Hoff and it's out of respect," he assured in an interview with British newspaper The Telegraph.

"I think people know that I've got a good heart. If I do something wrong, I'm the first to say 'Boy, did I f**k up.'"

David also counts Canadian superstar Justin Bieber as a fan. The 60-year-old star believes his younger supporters keep him current.

"He wanted to wear a T-shirt that said 'I'm with the Hoff at the MTV awards.' Can you believe that? I got Bieber Fever," he exclaimed.

"Because it means I'm current with the kids. Because it means I'm hip."
