Kim Kardashian's daughter, ugly and desperately in need of waxing......

Joan Rivers has made a particularly low blow by slagging off a defenceless baby.

The 80-year-old has branded Kim Kardashian's infant daughter North 'ugly' and 'desperately in need of a waxing'.

The comedienne joked about seven-month-old Nori - Kim's daughter with rapper fiancé Kanye West 

- as part of her latest stand-up comedy routine.

Joan explained how she had met the tot when the new mom brought her into the offices of the E! television network, where she hosts Fashion Police.

According to RadarOnline.com, Joan told her audience: 'That baby is ugly... I've never seen a six-month-old so desperately in need of a waxing.'

'North's eyebrows are thick, natural and amazing!': Kim was overwhelmed by comments that she had waxed her then-six-month-old's brows when she posted this photo of the infant to social media in mid-December
