Blac Chyna allegedly tried to drive away in Rob Kardashian's Range Rover after a meeting with their lawyers.

The model and the Keeping Up With the Kardashians reality star were both attending a meeting to resolve the custody battle for their nine-month-old daughter Dream when the incident is said to have taken place.

According to editors at TMZ, Rob and Chyna were at the meeting for several hours in the Century City law offices of Laura Wasser, who is representing Rob.

Two eyewitnesses have claimed that when Chyna left the office she saw Rob's Range Rover at the valet and became "agitated".

According to one of the eyewitnesses she got into the car and looked set to drive off but one of her lawyers reportedly told her "that's not a good idea" and, with the help of a valet, coerced her out of the Range Rover.

Chyna's lawyer Lisa Bloom told TMZ that the model did not try and drive away in the car, and denied she even got inside. However she did admit that Chyna was "agitated" when she saw the four-by-four, as she had actually given Rob the car as a gift.

Bloom admitted that Chyna had used some "choice words" when she saw the Range Rover but that was as far as her actions went.

Chyna wasn't the only one to buy a car as a gift during their relationship. Rob had also bought her a Ferrari and a Lamborghini when they were dating, but as soon as the couple split, she gave them back to him.

TMZ also cited Bloom as saying that the custody hearing about Dream is expected to be held next month, at which point the couple will also address allegations of domestic violence.
