44. Kendall Jenner's middle name is Nicole, after Nicole Brown Simpson, Kris' best friend.

46. Kris believes that her fridge is a "talking point" in her home, has a "personality of its own".
47. Khloé recently went into vivid detail about her, Kim, and Kourtney's pubic hair maintenance: "I'm all about the landing strip...Kim is completely bare, she lasered it off. I always think of Kourtney as large and in charge with a full '70s-style bush – it just matches her personality. But she swears that's just a joke and has a landing strip … sometimes."
48. And, finally, Kourtney's favourite homemade beauty remedy is putting mayonnaise on her vagina to "make it shine like the top of the Chrysler building".
