This supposed divorce is getting diiiiiirty! Now Blac Chyna is accusing Rob Kardashian of BEATING her!

Chyna says Rob hit her and then threatened her with the Kardashian wrath if she didn't keep quiet, according to a new TMZ report. So instead of squealing, Chyna did the next best thing -- she hooked up with a whole buncha dudes to piss off Rob!

One of those dudes was the rapper Ferrari, whom Chyna had reportedly been seeing for months -- even during the time she'd supposedly reconciled with Rob a couple weeks back. Rob says his baby mama sent him a sexy vagina selfie yesterday and then proceeded to hook up with her rapper friend to tease Rob and make him jealous.

Rob's freaking out now, saying he's going to try to bar Chyna from seeing the couple's daughter Dream, according to the report. On what grounds, you ask? Rob claims Chyna's doing drugs and is an unfit parent.

Rob even has some proof of Chyna's crazy antics -- he posted this video she sent to him with the message "Happy 4th" -- her in bed with a dude kissing him! We kinda think Rob's right -- what a psycho!




Then Chyna responded on Snapchat: "Rob u did all this but u beat me up and try act it never happen!!!!! U put hand on me I swear on god!!!! On my kids but I’m supposed to be quiet because you’re a Kardashian. The light will come to the light."

Then Rob threatened Chyna with not being able to see Dream again: "U will never see Dream again unless you stop the alcohol and drugs and cocaine and X and E. When was the last time u realized your daughter been with me instead of that crazy house that u bring men in and out. I never been this disrespected in my life by a woman. A woman I just paid 16K rent and Ferrari I just bought and lambo and 400K in Jewelry. Damn."

He went on to expose her post-baby weight loss surgery and set-ups with the paparazzi: "Everyone wonders how Chyna lost all that weight after the baby and she lies to everyone but no I’m such a great Husband that on our anniversary I paid 100K to do this surgery to get all everything fixed as much as they could. And then guess what she did after she was all healed when I was by her side the entire time. She left me and my baby which she had out of spite to get back at her other baby daddy. I can’t believe u would disrespect me like this."
