Kris Jenner calls reports that she once abused her children "ridiculous and not true."

The claims come from the alleged diaries of her late ex-husband Robert Kardashian, which his widow has turned over to In Touch magazine. In an entry from 1989, the high-powered attorney allegedly wrote, "Kris was kicking and beating [Kim] and said she was going to kill her. Kim was hysterical."

According to the magazine, Robert also wrote about Kris's alleged affair with a young soccer player named Todd Waterman and suggested she was an irresponsible mother who stayed out all night. "She doesn't leave a number in case of emergency. She doesn't care!" Kris's publicist questions the authenticity of the diaries, but Robert's second wife, Ellen Kardashian, claims the entries are real and were given to her by her husband before his death in 2003.
