The 59-year-old former Baywatch actor, who is currently in Sydney taking part in the second series of Celebrity Apprentice, said that he is a friendly person but does not like people interrupting him unnecessarily.
Hasselhoff told the Herald Sun: "Be gentle with the Hoff. If you see me making out with my lady, don't interrupt me; if you see me having dinner, wait until I'm done.
"I will come over and I am approachable, just kinda let me get through intimate moments and dinner first."
Hasselhoff is currently dating 32-year-old Hayley Roberts, who is staying with him in Sydney. The pair are believed to be spending this year's Australia Day (January 26) on Sydney Harbour.
Other stars taking part in this year's Celebrity Apprentice include past MasterChef contestant Marion Grasby, Amazing Race winner Nathan Joliffe, comedian Fiona O'Laughlin and Can of Worms host Ian Dickson.
