John Travolta has dismissed gay sex claims made against him by former employee Douglas Gotterba.

Earlier this year, it was claimed by Gotterba that the Hollywood star had been romantically involved with his ex-pilot - but Travolta has hit back at the suggestion, saying there is no foundation to the rumour.

He told The Daily Beast: ''This is every celebrity's Achilles heel.

''It's just about people wanting money. That's all. It happens on many levels.''

Travolta added that he's grown used to rumours circulating about his personal life and he's now largely unaffected by such speculation.

The actor - who is married to Kelly Preston - explained: ''Also, 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.''

However, Travolta, 60, did say that he is bothered when his family life is brought into the public spotlight.

He added: ''Sex stuff is always going to be interesting to somebody, but you stay away from family.''

Easy there, Gotterba.
