The 81-year-old comedienne takes aim at the 'Keeping Up with the Kardashians' star - who reportedly snubbed her at an event last month - by joking about her infamous sex tape in new book, 'Diary of a Mad Diva', and she also has harsh words for Kim's new husband Kanye West.
In extracts obtained by RadarOnline.com, Joan reportedly refers to President Barack Obama's 2013 inauguration by quipping: ''If I want to see millions of smiling black people, I'll set up a camera in the hallway outside Kim Kardashian's bedroom!''
Joan, who has her own reality show with her daughter Melissa Rivers, also claims she feels like ''one of the Kardashian girls - except I don't have a sex tape or black hair''.
The cut-throat star often takes shots at Kim, Kanye and the rest of the Kardashian clan on her E! show, 'Fashion Police', and once even branded the superstar couple's 12-month-old daughter North ''ugly''.
The insult reportedly led to Kim, 33, refusing to sit next to Joan at a presentation hosted by E! - which produces both their shows - in May.
Elsewhere in the book, Joan scolds absurd celebrity baby names, again alluding to the reality star and her rapper beau.
She wrote: ''Kanye West's new son is going to be named P*ssy in honour of where he came from.''
