5 Hollywood celebs you didn't know appeared in WWE

#3 David Hasselhoff

The Hoff addresses the WWE Universe on Monday Night RAW in 2010.

David Hasselhoff is a true icon of the 80s, with the Hollywood star even holding the Guinness World Record for the most watched man in Television.

Getting his big break on 'The Young and the Restless', Hasselhoff would move on to shows such as Knight Rider, solving mysteries with his advanced car KITT, before joining the equally iconic Baywatch.

Appearing as the guest host of Monday Night RAW in London, England, 'The Hoff' was reunited with KITT, and made some huge matches.

One of which included the upcoming Extreme Rules 2010 pay per view, announcing then-World Heavyweight Champion Jack Swagger (whom Hoff referred to as Jackie Swagger) would defend against Randy Orton.

Swagger would go on to retain the title, no thanks to the Hoff, a superstar of his own right in film and TV.
