Blac Chyna doesn’t seem to be letting her custody war with ex-fiance Rob Kardashian get to her. On Thursday the pinup was seen in a Sєxy look for a new pH๏τo shared to her 16.7M Instagram.

The former music video star was dressed in a white bra top and matching undies that showed off her array of colorful tattoos as she added gold kinky boots one of which rested on a boom box.

This comes just after Khloe Kardashian vowed to do ‘everything she can’ to help Rob win primary custody of his daughter Dream, whom he co-parents with Chyna.

Days earlier, the star wore black lace lingerie with red lipstick.

The 32-year-old sock designer filed documents in Los Angeles earlier this week asking to be the main carer of three-year-old Dream and sources have now said he has the support of his older sister Khloe.

‘Khloe has always been very close with Dream,’ a source told People. ‘When Rob had custody of her as a baby, Khloe often helped out. She really loves Dream.’

The insider added: ‘Khloe will do everything she can to help Rob get custody. She thinks this is best for Dream.’

Khloe, 35, has a close relationship with her nieces and nephews, including Dream, and recently documented a playdate between Dream and her own daughter True, 20 months, on social media.

The Keeping Up With The Kardashians star has always been close with her brother, who lived with her for several years.

In his documents, Rob asked a judge to limit the time Chyna spends with their daughter to just weekends with a nanny present as he believes she’s a danger and isn’t behaving appropriately around their little girl.

The reclusive star accused his former lover – who also has seven-year-old son King Cairo with her ex-partner Tyga – of regularly hosting parties at her home in front of Dream and invites strangers around to ‘get drunk with her.’

Rob believes Dream’s behaviour has changed recently as she’s started ‘naked twerking, and acting out Sєxual positions that she said her mom taught her’ as well as swearing and using language he insisted he never uses around her.

He also said his daughter arrives to him with messy hair and dirty teeth.

Rob’s paperwork states that Khloe can back up his allegations as she has noticed a behavioral change in Dream as she is ‘more in defense mode’ and is ‘decidedly more aggressive’ during her play dates with her cousins.

However, a lawyer acting for his client Chyna has blasted Rob for moving to take the tot away from her ‘hands-on, extremely loving’ parent.

Lawyer Lynne Ciani said: ‘So Rob Kardashian – who has … posted illegal revenge porn against Chyna – wants to take custody of Chyna’s beautiful daughter, Dream, away from her hands-on, extremely loving mother?

‘And Khloe Kardashian … wants to take her niece Dream away from her loving mother, Chyna? Oh, please.

‘Chyna will vigorously contest this latest despicable attempt to take away her daughter in a court of law, where she will keep prevailing against her ex-fiance Rob and the other malicious and vindictive members of his family.’

Rob filed documents in a Los Angeles court on Tuesday for full custody of his daughter.

Rob also reportedly asked the court to order Chyna to undergo random drug and alcohol testing, a move which was denied by a judge.

In his court filings, Rob made shocking claims about Chyna as a mother and said she has taught their little girl to mimic Sєxual positions, snorts cocaine with strangers and has a $600-a-day-alcohol habit.

He also ᴀsserts that Chyna is making for ‘an unsafe environment due to her unpredictable behavior’ and even makes violent threats to people in her home.’

Kardashian said that Chyna uses foul language in front of Dream, who has subsequently repeated phrases such as ‘What the f***?’ and ‘b***h.’

And he said in court docs that a person who used to work with Chyna said that the Lashed entrepreneur spends about $600 on booze a day,

He added that she is usually drunk, and has finished a full bottle of Hennessy in one sitting.

Dream was involved in a physical fight with another kid last month, which Rob said is indicative of her mother’s influence.

Rob is asking the court to mandate Chyna take drug and alcohol tests a half-hour before visits; and that the nanny is granted legal power to terminate the visits in cases of violent or aggressive behavior when the child is present.

Chyna told RuPaul in June that ‘co-parenting is good’ with both Tyga and Rob, as they’re ‘all in a good place.’

‘With both of my baby fathers, we have a mutual agreement and everything runs smoothly,’ she said.

Rob and Chyna welcomed Dream in November 10, 2016, but they split in February 2017
