John Travolta is being accused of sexually assaulting a man

The supposed victim’s shocking description of the incident threatens to blow the lid off Travolta’s long-rumored double life as a happily married family man.

It took place at the LaQuinta Hotel in Palm Springs, California, when Travolta demanded a deep body massage at the facility’s spa, which had been opened after midnight for the actor’s private use on Feb. 15, 2000.

But the man claims Travolta wanted a more intimate rubdown.

During the massage, the star kept removing the towel “exposing” his bare buttocks, according to the never-before-seen official report.

After the masseur administered a body scrub treatment, he says Travolta told him “he was very attractive and that he had gotten him ‘excited.’”

Travolta then asked the masseur to join him in the spa’s steam room, “so he wouldn’t be alone,” says the man, who complied with the request.

Totally naked after dropping his towel, Travolta then offered to demonstrate his own massage techniques on the masseur.

As the man lay on his stomach, “Travolta reached under his towel and began to rub his inner thigh.”

Then the actor “began rubbing [the masseur’s] bare buttocks as well as in the groove between.”
