'I've never seen a baby so desperately in need of waxing': Joan Rivers sinks to new low as she slags off Kim Kardashian's 'ugly' daughter North

She's known for her off-handed and sometimes downright offensive comments, but comedienne 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.

'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

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.'
When the 33-year-old first revealed a full-face photo of her child on social media in mid-December, she was inundated by comments that she had waxed the baby's perfectly groomed brows.

One proud mama: The 33-year-old shared some more adorable never-before-seen photos of her genetically-blessed only child when she was interviewed on The Ellen DeGeneres Show last week

Taking to Twitter to defend her six-month-old’s appearance, she wrote: ‘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!
‘I'm kidding!!! Its pretty sick for people to insinuate that I would wax my daughters eyebrows. They are thick, natural and amazing!’
Joan's joke is unlikely to go down well with Kanye, who is fiercely protective of his daughter and vowed shortly before her birth last June that he was determined she would enjoy a normal childhood and not let people take advantage of her.

Not everyone's laughing: The 80-year-old - here with Fashion Police co-star Kelly Osbourne (centre) and daughter/producer Melissa Rivers - has made a career out of her humour, but her jokes about an innocent child have pushed the limits

The 36-year-old said: 'This is my baby. This isn't America's baby.'
Explaining his fatherly duties further, he added: 'One of the things was to be protective, that I would do anything to protect my child or my child's mother. As simple as that.'
Kanye was also upset recently when Kim dressed North in a two-piece swimsuit to take her for her first dip in a pool.
She revealed during an interview on The Ellen DeGeneres Show last week: '[Kanye] is a little uncomfortable with North wearing a bikini. I tried it once and it did not go over well. It has to be a one-piece.'

Daddy's little girl: Kanye West is said to be very protective of his only child and wasn't at all happy when his fiancée put the seven-month-old in a bikini recently, with Kim revealing it 'did not go over well'

Protective parents: Kim and her 36-year-old rapper fiancé - seen here in Paris on Sunday - are yet to respond to Joan's 'joke' though they are sure to have plenty to say on the matter
