The Kardashians have rubbished Blac Chyna's accusations in their ongoing legal feud.

The 29-year-old model - who is the mother of Rob Kardashian's 14-month-old daughter Dream - has accused the reality TV family of defaming her and sabotaging her show 'Rob & Chyna', but Kris Jenner, Rob and Kim Kardashian West have now hit back in their bitter row.

The celebrity trio - who are named as the defendants in the suit - have countered Chyna's claims by saying they are "bald conclusions that have no factual support," DailyMail.com reports.

Chyna - who was involved in an on/off relationship with Rob from January 2016 until February 2017 - filed her original suit in October last year.

The former stripper claimed the Kardashian family was responsible for the cancellation of her show, which was axed after just one season.

According to Chyna - whose real name is Angela White - the US TV network E!, the show's production team and Rob were all open to shooting a second season before it was suddenly cut.

Chyna alleged that the Kardashians have used their "fame, wealth, and power" to undermine her TV career.

But the Kardashians have dismissed her claims, insisting even Chyna had said plans for a second season  were never officially confirmed.

Court papers read: "Plaintiff [Blac Chyna] affirmatively alleges ... that on 'February 8, 2017, the E! Network sought a seven-month extension' of its option to engage plaintiff's services on a second season of Rob & Chyna, which, according to plaintiff, gave the network until October 16, 2017 to decide whether to pick up a second season of the show."

Meanwhile, Chyna has also accused the Kardashians of defamation, after they alleged that she left Dream at home while she went to a party.

But the Kardashians insist they never made that claim and instead said Chyna left the baby with a nanny.

Attorneys representing the famous family also said that Chyna's latest court filing represents her second attempt to "plead viable causes of action" without actually fixing them.
