Kim Kardashian’s late dad — O.J. Simpson legal eagle Robert Kardashian — painfully documented his epic battles with her mother, Kris, over Kris’ alleged affair with former soccer pro Todd Waterman, and the details are coming to light for any Kardashian obsessives out there. According to “The Complete Kardashian Diaries,” In Touch’s “Collector’s Special,” Robert kept notes throughout 1989 and ’90 detailing his very rocky relationship with first wife Kris, in which he refers to her simply as “K.” “K w/ Todd all weekend,” one of the published handwritten entries reads, followed by notes saying, “slept on floor b/c she was so drunk,” “kicked her out,” “11th anniv. — what a joke” and “Kris slept out again — never home at all. Kids don’t even ask where she is.” The diaries even reflect that Robert “caught K at Todd’s apt” and “Told her I wanted a divorce.” “For two years Robert jotted down notes on his increasingly volatile marriage,” says the new publication. Also included in the 100-page Kardashian cache are private family photos of now-famous kids Kim, Khloe, Kourtney and Rob, as well as an interview with Kardashian’s widow, Ellen, and even a psychologist’s full report on the family. Kardashian’s rep declined to comment.
