Damn! This is the kind of allegation that would make your grandma throw her purse at you if you repeated it. No one likes to hear the Kennedy’s slagged. A new book by Rob Littell, a “close pal” who attended Brown University with JFK Jr., alleges that John John would probably have put his penis in a microwave-warmed melon if it was handy. Before we get death threats, we’re only reporting on what this dude wrote in his book. He claims John didn’t consummate with Madonna because of lack of protection and had flings with trannies, guys and hookers. Supposedly, he met up with Madonna in a hotel motel Holiday Inn in 1988.

“They were working their way around the bases, and as they rounded third and headed for home, she asked him if he had any protection. He didn’t, so now they began discussing how they were going to get a hold of a prophylactic,” Littell tells the author.

“She was still legally married to Sean Penn, and he had a steady girlfriend . . . They were afraid of being busted. They couldn’t very well just meander into a pharmacy and ask for a pack of Trojans. They were too well known . . . To John’s great chagrin, the relationship was never completed.”

Fame can be a cock-blocker. And Madonna’s just the tip of the iceberg. Keep reading.
