As I put in the Rock is gay thread, Travolta has an open marriage where he is allowed to sleep with other men. This allows Kelly to sleep with other men.
As I said, they were in a famous New York hotel some years back. Kelly was up in their room having sex with her male personal trainer. John was down in the gym's sauna hitting on a guy who almost beat the shit out of him.
The guy (name escapes me) who wrote an unauthorized biography on Travolta supposedly found over a dozen men who had had sex with him. A number of them were gay porn stars.
Mike Walker of the National Enquirer once said that Travolta was well known for hitting on male cast members in some of his movies.
He is gayer than Anderson Cooper.
