The Kardashian family are hitting back at alleged claims of racism made by Blac Chyna over their E! show Rob & Chyna, just one day after Gabrielle Union filed a discrimination complaint against NBCUniversal, which also owns E!.

Chyna, 32, is accusing the Kardashian-Jenner family of racism, claiming it is the real reason why her reality show Rob & Chyna didn't get renewed for a second season on the network.

In response to the claims, Kardashian family attorney Marty Singer tells DailyMail.com: 'This is a 2 year old lawsuit in which Chyna has changed her defense more times than we can count.'

'Sadly, unsurprising to anyone, she has stooped to a new low, changing her defense to try to leverage the emotions and pain of the moment, insulting the pain and suffering of real victims of racial injustice and systemic racism.'

Singer added: 'We take these allegations very seriously and once again, there is no Rob & Chyna show if there is no Rob & Chyna.'

Neither NBC nor E! are listed as part of Chyna's original lawsuit from two years ago, and the new claims have emerged in a new statement, not a new lawsuit, by her attorney.
