If you've been keeping up with all the latest gossip this week -- or even if you've just been near the internet -- you know that things aren't going so well between Rob Kardashian and Blac Chyna right now.
They're actually going really, really badly.
The issue, at least the current one, started when Rob felt the need to vent about his strained relationship with Chyna on Instagram.
He apparently has a number of problems with his ex-fiancee and the mother of his child, and he wanted to tell us about every single one of them.
For instance, Rob claimed that Chyna was still sleeping with him, and that she's also sleeping with a few other men -- and she's even bringing those men in her home with her children.
In another section of his big long rant, he said that he paid thousands and thousands of dollars for plastic surgery for Chyna after she gave birth to dream.
Surgery that apparently messed up her nipples.
Rob said that Chyna does all sorts of drugs, and that she drinks a lot, and that she cheated on him, and that he pays her bills and he spent nearly a million dollars on her while they were together.
He also shared a few nude photos of her -- and that crossed a whole different line.
Now Blac Chyna is taking the feud to the court system, and rightfully so.
It was illegal for Rob to post those photos of her, and she wants to file a restraining order against him because, as she claimed in her case, she's scared of him.
Partly because of his unhinged ranting, and partly because she said that he's been violent with her.
Rob could be prosecuted, Chyna could lose custody of her kids ... there's a lot at stake here.
And, according to a new report from Hollywood Life, Chyna may be preparing to make things worse.
With a sex tape.
"Blac is shopping a sex tape that doesn't involve Rob," a source claims.
"She wants to use it to humiliate Rob and also make a pretty penny off of it."
Could you see her taking things that far?
Honestly, it doesn't sound like much of a stretch.
Chyna's always been very comfortable with her sexuality, and if any of Rob's statements about her are to be believed, there's nothing she won't do in the the name of pettiness.
Or in the name of making money.
And if she really is considering a sex tape, Vivid Entertainment, the fine company that brought us the sex tapes from Kim Kardashian and Farrah Abraham, are willing to distribute it.
"We think Blac Chyna would be great in a sex tape and many people are fascinated by her," says Vivid CEO Steven Hirsch.
"We would definitely like to see whatever tape is out there or work with her on something new."
Brace yourself, Rob ... sex tape or no sex tape, things are probably going to get worse real soon.
