Rob Kardashian is on the war path.

According to TMZ, the couple are at odds again, with Rob claiming that Chyna sent him a pic of her vagina on Tuesday, only to cheat on him with a rapper named Ferrari afterwards. Apparently, Ferrari has been open about his fling with Chyna, so Rob definitely isn't making this up.

The interesting angle here is that Ferrari says he's been hooking up with Chyna for months now, a timeline that includes when she reconciled with Rob. Based on his Instagram rant, Rob is going wild, threatening to block Chyna from seeing their child ever again. He's also alleging that she's on drugs and out of her mind at least a little bit. Follow the drama below.
