Baby mama drama!

Tyga has filed papers to change his custody agreement with son King Cairo's mom Blac Chyna after her recent arrest, TMZ reports. The rapper believes he is the more fit parent after Chyna's run-in with the law in Austin last week, which stemmed from being drunk and disorderly and being in possession of ecstasy pills.

Kylie Jenner's boyfriend wants custody of King Cairo during the weekdays, and he will allow Chyna visitation on the weekends. Sources tell the site T-Raww's latest move has nothing to do with Chyna's new relationship with Rob Kardashian. The hip hop bad boy is allegedly cool with the mother of his child dating his girlfriend's brother, he just isn't down with her wild lifestyle.

That poor kid! His parents are Tyga and Blac Chyna!
