Actor John Travolta has denied having sex with his former employee Douglas Gotterba. He says ‘there is no foundation to the rumour’. In an interview with The Daily Beast, Travolta responded to the claims made by Gotterba earlier this year, reports femalefirst.co.uk. ‘This is every celebrity's Achilles heel. It's just about people wanting money. That's all. It happens on many levels,’ he said. Travolta added that he's grown used to rumours circulating about his personal life and he's now largely unaffected.
