The notorious O.J. Simpson reportedly claimed a "hot-tub hookup" he enjoyed with Kris Jenner in the early 1990s saw the Kardashian matriarch hospitalised because of the size of his manhood,Daily Mailreports.
O.J.'s former manager Norman Pardo said the disgraced NFL star told him about the alleged romp - said to have taken place while O.J. and Kris were married to Nicole Brown and Robert Kardashian - and boasted he "f***ed that B until I broke her", according to theNew York Post.
The tryst reportedly ruined their respective marriages and damaged the couple's longstanding friendship with each other.
Mr Pardo, who managed O.J. from 1999 until 2012, made the claim in his sensational documentaryWho Killed Nicole?, which details the mysterious 1994 murder of Nicole Brown and her friend Ron Goldman.
According to Pardo, the famous foursome was enjoying an evening in a jacuzzi whilst on vacation together when Robert and Nicole headed to bed leaving Kris and O.J. alone.

"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***ed that B until I broke her," Mr Pardo recalled.
He further claimed momager-to-be Kris had to be taken "to the hospital at two or three in the morning" because of the damage inflicted by his enormous manhood.
