ENQUIRER EXCLUSIVE WITH ALL THE DETAILS as the JOHN TRAVOLTA gay sex scandal goes MILE HIGH as male pilot has con­fessed to carrying on a six-year sexual affair with the actor – and Travolta’s longtime personal as­sistant confirms the “Grease” star is gay! PLUS:  another accuser!

In a desperate bid to cover up his gay af­fair with pilot Doug Gotterba, Travolta cooked up a phony romance with then 16-year-old actress Brooke Shields, sources say.

But Gotterba, who worked for Travolta for six years, admit­ted their secret affair to the actor’s former secretary Joan Edwards.

And in a blockbuster ENQUIRER interview, she’s be­come the first person in Travolta’s inner circle to publicly acknowledge that the 58-year-old star is homo­sexual.

I worked for John Travolta from 1978 through 1994,” Edwards told The ENQUIRER.

“I did everything for him, includ­ing taking care of his personal and professional schedules. Of course, I knew he was gay. It never bothered me.”

Edwards, who lives in the Los An­geles area, confirmed that Gotterba began working for the “Hairspray” star as his pilot in 1981.

“That’s how I met Doug,” she said.

“We both worked for John at the same time. Doug is a wonderful guy and we are still good friends. He told me that John was gay and they had a sexual relation­ship.”

The ENQUIRER has learned that Gotterba also revealed intimate details of his hush-hush romance with Travolta to another male lov­er, Robert Britz.

Britz claims that he was a se­nior at a private boarding school in Santa Barbara, Calif., when he met Gotterba through a newspaper personal ad in 1994. Britz also says Gotterba showed him a home video of him with Travolta in a hotel room.

“Doug told me right at the begin­ning of our relationship that he’d had a homosexual rela­tionship with John Travolta in the 1980s,” Britz – an actor, model and musician – told The ENQUIRER.

“Doug said John was constant­ly grabbing at his genital area, but he put up with John’s sexual advances because working for him was ‘lucrative.’”

While they were at Gotterba’s home, the pilot showed him a home video of Travolta and also several mementos from the actor, Britz said.

“I personally saw about two minutes of Doug’s home video showing John Travolta sitting at the end of a bed with his shirt off,” Britz told The ENQUIRER.

“There were plates of food in front of him. The video appeared to be shot in a hotel room.

“Doug also showed me a black leather jacket from ‘Staying Alive’ and a white jacket from ‘Saturday Night Fever’ that he said John had given him.”

Gotterba further claimed that he chauffeured the actor to gay sex stores, said Britz.

“Doug made it clear that it was very lucrative for him to be what he called John’s ‘personal right hand man’ and homosexual partner,” said Britz.

But after about five years, Gotterba said Travolta’s personal habits turned him off, according to Britz.

“Doug said that he hated sleeping with John because his body was very hairy, and he didn’t like the way John smelled,” Britz revealed.

“John also would become heavy between movies. Doug called him ‘huge’ and said it turned him off.

“After a few years, Doug grew apart from John sexually, and John’s ad­vances eventually started to repulse him. The relationship ended shortly thereafter.”

When contacted by The ENQUIRER, Gotterba, 60 – owner of Santa Barbara Executive Jet, a private charter service in Carmarillo, Calif. – confirmed that he’d worked as a pilot for Travolta for six years in the 1980s.

A year after their relationship ended, Tra­volta met “Jerry Maguire” star Kelly Preston on the set of the movie “The Experts” and they tied the knot in 1991. But now, sources say the gay sex scandal has shat­tered their marriage.

 Although Travolta’s attorney vehemently denied the claims, several more men have come forward with similar accusations against him.

But until now, there’s never been any indication that John had engaged in a long-term homosexual relationship,” an insider told The ENQUIRER.

“Kelly has to worry that this man may put even more details of her husband’s affair with him in a tell-all book. And what if he has video and photos of them to­gether? For Kelly, this is a nightmare that just gets worse by the day.”
