Joan Rivers may have taken a joke too far when she mocked Kim Kardashian and Kanye West's baby girl, North West. 

The 80-year-old comedian and Fashion Police co-host reportedly took a shot at North during a standup show on Friday, Jan. 17 at the Saban Theater calling the baby "ugly."

Rivers said to the audience that the Kardashian clan had recently visited E!'s offices in Los Angeles. 

"That baby is ugly ... I've never seen a 6-month-old so desperately in need of a waxing," she said to the audience, according to Radar Online.

Rivers comment comes weeks after Kardashian had to defend false claims that she altered North's eyebrows after she uploaded a pic on her Instagram in December. 

"Do people really think I would wax my daughters eyebrows so young? Come on, I'd wait until she's at least 2 1/2!" Kardashian said. 

Kardashian or Kanye have yet to address Rivers' comment. 

During a recent appearance on Ellen, the 33-year-old reality star was honest about how difficult her pregnancy was. She revealed that before getting pregnant, she wanted to have at least six children, but carrying North has changed her mind.

"[Women who say pregnancy is easy] are lying," Kardashian said. "They are lying to you. I'm telling you. Kourtney said that, my mom said that. I was literally giving birth and I looked at my mom and I said, 'I'm going to get you a medal. You deserve everything."
