A representative for Kim Kardashian’s mom Kris Jenner has shot down reports suggesting her late ex-husband accused her of child abuse and adultery in 24-year-old journal entries.

Robert Kardashian's widow Ellen has come forward with his diaries, which appear to suggest his former wife physically abused their kids, Kim, Kourtney, Khloe and Rob, and abandoned a family Christmas to spend time with her alleged lover.

The damning excerpts from the late lawyer's journal have been obtained by editors at In Touch magazine – and Ellen has verified they're authentic.

The diary entries read: "She (Kris) doesn’t leave a number in case of emergency. She doesn’t care! She left (the) kids and screwed all night!"

He added, "Kris couldn’t get her act together" (to spend Christmas with her children). I was home alone with 4 kids."

Robert also alleged Kris abused Kim, and wrote, "Kris was kicking and beating her and said she was going to kill (Kim)! Kim was hysterical."

However, Kris, who has been married to Olympian Bruce Jenner since 1991, denies the allegations

Her publicist tells the New York Daily News, "We have no knowledge of these diaries existing and these accusations are ridiculous and not true."

Robert Kardashian divorced Kris 13 years before he lost his battle with cancer in 2003.
