Last night, Blac Chyna went off on "whack ass b-tches" who have been critical of her relationship with Rob Kardashian.
You don't have to be Sherlock to deduce that some of the whack asses that Rob is talking about belong to Rob's sisters.
After all, the Kard clan has plenty of reasons to take issue with Rob's new relationship, the most obvious of which is Blac's ongoing feud with Kylie Jenner.
But there's also the possibility that Blac is just flat-out bad for Rob.
The troubled 28-year-old has been struggling to adopt a more healthy lifestyle after living the last 18 months in hiding and being diagnosed with diabetes back in December.
Blac initially claimed that she was helping Rob get back into shape - cooking him healthy meals and working out with him at her in-home gym.
Last week, however, Blac was arrested for being drunk and disorderly at Austin International Airport, and was found to be in possession of two Ecstasy pills.
Not exactly the sort of behavior you look for in a health guru/life coach.
Despite her recent troubles, Rob has reportedly assured his friends that Blac is good for him and that he's healthier and more sober than he's been in years.
Of course, when Khloe Kardashian kicked Rob and Blac out of her house last week, she reportedly found the place strewn with liquor bottles.
According to TMZ, Rob tells his friends that sober is a relative term, and while he's still drinking, he's no longer engaging in the sort of drug use that led to his current health woes.
Baby steps, we guess.
