I'm amazed that people are acting like these gay revelations are something new. Travolta was outed years ago, when he was on the cover of the National Enquirer for his affair with gay porn star Paul Baressi.
Yup, and Carrie Fisher outed him too not that long ago...a couple years ago, if at that. She basically said "we all know about John..." etc. in reference to rumors that were going on around that time.
From industry folks, it seems it's common knowledge in the industry that John loves men and has been hooking up with them consistently since his tv days, supposedly. I was weary at believing it at first, but it's come up so many times over the years that there seems to be too much smoke for there not to be some sort of fire.
I've read story after story around sites of folks who have worked at various hotels/gyms that he stays at when shooting films, and the stories basically are all the same...picking up men and taking them back with him.
