OJ Simpson is finally admitting to having s*xual relations with Kris Jenner, the then-wife to OJ's lawyer and longtime friend Robert Kardashian.

And in true OJ fashion - he's not being very gentlemanly by talking about their encounters. According to OJ, he allegedly damaged Kris internally - because his p*nis was too large for Kris to handle.

Here's how the Ny Post's Page Six is reporting it:

“‘O.J. said he stood up, pulled his shorts down and, I’ll give you exactly what he said: ‘Her eyes bugged out of her head and I f–ked that B until I broke her,’” Pardo recounts on camera in a segment previewed exclusively by The Post.

“That was as messed up as you can possibly get.”

The alleged one-night stand had longstanding consequences for the four glamorous pals.

“From what I’m understanding, from what O.J. told me, everything was great up until [the] little fling that they had,” says Pardo, 55, who says he managed Simpson from 1999 to 2012 and has 70 hours of videotape of his former friend.

So what exactly did he mean he "broke" her?

Simpson said “they had to take her to the hospital at 2 or 3 in the morning,” Pardo continues in the movie. “She came to [O.J.’s] room and said, ‘Can you take me to the hospital?’ He said, ‘No. Have Rob do it.’”

Simpson, now 71, boasted of the rendezvous — and the damage his menacingly large manhood had apparently inflicted — to Pardo during a 2003 limo ride from Raleigh, NC, to a paid appearance at an Atlanta nightclub, the ex-manager told The Post.

And the timeline - when this happened? Around the year 1984. That's the year that Khloe Kardashian was born, in case you're wondering.
