Travolta's denial.

"Plaintiff's attorney has filed this suit to try and get his 15 minutes of fame. John intends to get this case thrown out and then he will sue the attorney and plaintiff for malicious prosecution."

But John Doe is fighting back, telling RadarOnline.com on Tuesday: “I have proof to support the truth that I’m telling.”

He refused to divulge what that proof was, RadarOnline.com reported.

LIST: John Travolta's filmography.

The lawsuit claims Travolta booked the massage from an online advertisement and offered to pick the man up in his black Lexus SUV. The pair then drove to the Beverly Hills Hotel before continuing on to the actor's personal bungalow.

Travolta allegedly stripped naked in front of the masseur before beginning the massage. After about an hour Travolta allegedly rubbed the man's legand touched his genitals.

The plaintiff said he told Travolta he would not have sex with him but claims the "Saturday Night Fever" star responded by offering to perform a sexual act.

The lawsuit goes on to say that Travolta subsequently masturbated and told the masseur that his Hollywood career could only progress "due to sexual favors."

The masseur is seeking $2 million plus punitive damages.

Travolta, who is an ambassador for Australia's flagship airline Qantas, has been married to actress Kelly Preston since 1991. The couple had three children together but their oldest son Jett died tragically from a seizure in 2009.

Preston gave birth to the youngest of their children, Benjamin, in November last year.
