Blac Chyna is facing felony drug possession charges after cops found several grams of ecstasy pills in her sunglasses case while she was detained for drunk and disorderly conduct at Austin-Bergstrom airport last weekend, and her ex Tyga is trying to use the debacle against her in court.
TMZ reports that the "Rack City" rapper is filing for increased custody of the former couple's son, King Cairo, using the Austin incident as evidence that Blac is an irresponsible mother. Tyga wants full custody of King and Blac to have visitation rights on the weekends. Right now, it's the other way around.
The site also reports that a recent Snapchat video showing Chyna's new man, Rob Kardashian, playing with King Cairo has nothing to do with the move. He's not jealous of his baby's mother's new relationship — in fact, he reportedly thinks Rob's a good guy — but believes Chyna's drinking and drug use is the problem.
Chyna, meanwhile, claims that she has no idea how the ecstasy pills wound up in her luggage and hopes to have the charges dismissed. 
So while the rest of the Kardashian-Jenner clan seem to be making amends with their enemies, looks like the war is just heating up between Blac and Tyga.
