Kris Jenner once kicked and beat up an eight-year-old Kim Kardashian. This and other lurid allegations form part of the explosive extracts from what are believed to be the late Robert Kardashian’s diary.

According to RadarOnline, excerpts from the diary were published in a weekly US magazine.

In an entry dated August 24, 1989, Robert Kardashian allegedly wrote: “Kris was kicking and beating her and said she was going to kill her! Kim was hysterical. Kris then got on the phone and said, ‘Kim if you don’t get up here right now you are dead!’”

The diary entries also detail the Kardashians’ marital problems, alluding to Kris’ well-publicised affair with the then 24-year-old Todd Waterman. In the diary, a forlorn Robert accused Kris of abandoning her children.

“She doesn’t leave a number in case of emergency,” he allegedly wrote. “She doesn’t care! She left [the] kids and screwed all night!”

In September 1989 entry, Robert claims his daughters called him crying numerous times after their mother forgot to pick them up from school because she was with Waterman.

Robert and Kris finally ended their marriage in 1991. Later that same year, Kris married her current husband, former Olympian Bruce Jenner.

The diary was made public by Robert’s ex-wife Ellen Kardashian. She claims that Kris Jenner often took her frustration out on her kids – something, she says, the girls resent to this day.

Ellen married Robert before he died in 2003 following a battle with cancer.

A representative for the Kardashians denied any knowledge of the diary’s existence and stated that the allegations were untrue.

However, Khloe Kardashian Odom took to her Twitter account on Thursday to blast Ellen for her claims.

Khloe tweeted: “How can such a piece of trash even mention my father's name. You married him on his death bed when he was not even aware of his surroundings.

“You should be hiding in shame for all of the lies you sell to the tabloids.

“You have no right to even mention our names especially my mothers! We don't know you!!! How dare you spread such lies! You are a disgrace.

“10 years after my fathers passing & now that she has filed for bankruptcy... NOW she sells FALSE stories. Hope that money buys you water in hell (sic).”

Kim, 31 - who is expecting her first child with Kanye West - also blasted Ellen, tweeting: “10 yrs since dad passed & this woman he married 4 2 wks before he died needs to get a job instead of trying to destroy my family w fake stories.” - Bang Showbiz IOL and Bang Showbiz
