The pilot claiming he had a six-year gay affair with John Travolta is negotiating to reveal all the details in an explosive tell-all book, reports say.
Doug Gotterba was John's pilot in the '80s, and according to Doug, his former secretary and Doug's ex-boyfriend, he and the actor were lovers.
The Enquirer reports that Doug already has two writers lined up to help him tell his story, "confirmed his desire" to expose everything he knows.
"It could be a marriage-ender," an insider told the Enquirer, saying that the book could be career-crushing and devastating to John's wife, Kelly Preston.
"Even though she wasn't married to John at the time, she's already been terribly humiliated by this ugly scandal that doesn't seem to end."
"A book by a man who John carried on with for years could simply be too much."
After all, it follows a month that saw two masseurs come forward to slap John with lawsuits - later dropped - claiming he was sexually aggressive.
Since then, more men have stepped forward claiming much of the same, though the actor vehemently denies all allegations via his attorney.
