Earlier this year, his former employee, ex-pilot, Douglas Gotterba, said he was romantically and sexually involved with the Pulp Fiction star, but Travolta has denied the allegations and now the pair are involved in a pending lawsuit.
"This is every celebrity's Achilles heel,” Travolta told The Daily Beast.
"It's just about people wanting money. That's all. It happens on many levels."
The 60-year-old, who is married to Kelly Preston, added: "I don't care that much about it. Other people may attack it back more than I do, but I let all the media stuff go a long time ago because I can't control it.
"I think that's why it persists, to some degree."
