The Baywatch Sex Tape No One Wants: Jeremy Jackson

The promise of any Baywatch sex tape sounds very exciting, except one that stars -- Jeremy Jackson.

Who? David Hasselhoff's son...Hobie. Remember?

Anywhoo, TMZ has learned that Hobie's career did not end with Baywatch: Hawaiian Wedding in 2003, he also starred in a never released sex tape with Vivid porn star Sky Lopez.

Hobie told TMZ, (You ready for this shit?)

"Listen, this video was made by my best friend. Between me and a casual sex partner who just so happened to be a former porn star. I was later physically threatened if I didn't turn the DVD over to some drug addicted thugs.

"They said, 'Sky wanted it back and didn't want to ever be seen as a porn star, that she had turned to God and was changing her life.' So I gave it up for HER and so they would not beat me up and 'make my life hell' as they had threatened. I was blackmailed. This private recording becoming public kinda sucks. But I thought people out there should know the truth and how far some people will go to make a quick buck."

Why has the tape never been released? Because no one wants to buy it, not even Vivid who released the dreaded Jimi Hendrix sex tape.
