Serena Williams, Kim Kardashian ,braless Joan Smalls and Vittoria Ceretti at PFW's Balenciaga show

Tennis star Serena Williams, 42, also made an appearance in a bright blue fur coat and a plain black dress underneath.

It comes after earlier this year Kim was blasted by fans after revealing she has become an ambassador for Balenciaga, one year after the brand faced controversy for an advert featuring children and BDSM items.

The reality TV star announced her partnership with the label, helmed by creative director Demna Gvasalia, in January.

The mother-of-four previously refused to cut ties with the fashion house but said she was 'shaken and disgusted' by the images which sparked a backlash against the brand.

After announcing her new partnership many fans were left disappointed by the decision and hit back at her statement, in which she wrote that her relationship with the brand was built on a 'commitment to doing what's right.'

'Of all the brands, she had to choose the one with child abuse allegations. Not even surprised though…' one person wrote, while another branded her a 'hypocrite' adding, 'Money is all that matters to her.'

Another person accused Kim of throwing her 'morals out of the window' for money, while someone else added, 'Anything for money and a higher net worth I guess.'

'Where's she gonna keep all the money and fame when she's gone?'

'So we forgot about the kid bondage thing? lol' one commentator inquired.
