*Poor Rob Kardashian. He probably rues the day he hooked up with Blac Chyna.

Let’s just say she hasn’t been good for him. But then again, it could be argued that he wasn’t good for her, either.

Here’s what dude has to deal with now. Chyna, 29, is set to file an “explosive” countersuit against Kardashian in the wake of him accusing her of abusing drugs and trying to strangle him.

“Chyna hired a team of lawyers to help her fight back against Rob,” a source told RadarOnline. “He’s rich, with all of the Kardashian money, but she knows his secrets, and now she’s not going to keep them.

“She’s going to file an explosive counter lawsuit for millions that will expose all of Rob’s lies.”

The source says Blac Chyna is holding off until October 27, which happens to be one month after Kardashian’s lawsuit against her. Apparently she wants to make sure she’s got all her stuff together.

“Chyna is gathering all of her evidence, making sure her story is solid and better than the one that Rob told,” the source added. “She’s going to wait until the end of the deadline to file her suit. She has about three more weeks.”

“She is going to stick it to Rob twice. She will file a response, and her own lawsuit. This will get ugly.”

If you missed it, here’s what the issue is. Kardashian, 30, is accusing his baby mama trying to choke him with an iPhone cord. He adds that she hit him in the head and face and threw a metal chair at his Bentley as he tried to flee their home last December.

Well, whatever the situation is, Blac Chyna is out for revenge … and a payday. Here’s what a friend of Chyna previously told RadarOnline:

“Blac Chyna wants Rob to pay for what he did to her. She isn’t afraid of him,”
