Joan Rivers has shown dislike toward Kim Kardashian and Kanye West like never before.

Kim Kardashian Shares Cute Picture Of North West For First Birthday

The 81-year-old comedienne and host of E!'s Fashion Police penned it in her new book Diary of a Mad Diva. The book is full of jabs and jokes toward the newlywed couple, who she has made it clear that she does not care for.

Radar Online reported that in the memoir, Rivers opens up about President Barack Obama's Inauguration. She slams Kardashian, saying, "If I want to see millions of smiling Black people, I'll set up a camera in the hallway outside Kim Kardashian's bedroom!"

As harsh as that was, she doesn't even come close to stopping there.

She also added that she can relate to the Kardashian/Jenner clan as she tapes her own reality show Joan & Melissa: Joan Knows Best and adds that she feels "like one of the Kardashian girls, except I don't have a sex tape or black hair."

Rivers also takes digs at West, going as far as dedicating the entire book to him because she knows he will never even read it. She was most likely referencing the time West admitted that he is a "proud non-reader of books."

Rivers stops at no end when it comes to slamming Kardashian and West and at one point even brought their 1-year-old daughter, North, into it when she called her "ugly" at a stand-up event in New York City last month.

She also makes Robert Pattinson, "stupid" Jennifer Aniston and Lena Dunham the butt of her jokes.
