Blac Chyna and Rob Kardashian looked as though they were going to handle their split at least civilly, but all that changed on Friday (August 18).

According to TMZ, Chyna was so fed up with how proceedings were going when she and her lawyers attended a custody hearing along with Rob and his legal team that she tried “hightailing” out of the parking lot in Rob’s Range Rover.

Two eyewitnesses claim that when Rob called for his vehicle to be pulled up for him, but was still in the building, BC – who left the meeting first – hopped in was about to put the pedal to the metal when one of her lawyers advised her not to.

"That's not a good idea," she reportedly told Blac Chyna, who with the help of a valet finally got out of Rob’s whip.

Lisa Bloom, Chyna’s attorney who also attended the custody battle proceedings, denies that her client attempted to drive off in the Range, but did acknowledge that she was pissed upon seeing it.

The vehicle was a gift to Rob from Chyna, but was never returned to her after their split, even though she returned the Lamborghini and Ferrari Rob had gifted her. Bloom said Chyna had a few “choice words” when she saw the Range Rover, but it ended there.

Lisa Bloom also says the custody hearing is going down next month and even revealed that she plans to raise allegations that Rob committed domestic violence during the couple’s relationship.
