Tyga's Ex Blac Chyna Is Probably Doing Sex with Rob Kardashian and His Family Isn't Happy

Blac Chyna—model, best friend of Amber Rose, and mother of Tyga’s son—Instagrammed a photo of herself today wrapped in a tattooed arm that suspiciously looks a whole lot like the arm of Rob Kardashian. Who knew that one little pic could be such a major “fuck you” to E!’s first family?

Blac Chyna’s ex Tyga, of course, dates Rob’s half sister, Kylie, and—for that reason and others—Blac Chyna has never been on good terms with the bulk of the Kardashians.

People sums it up thusly:

Here’s a quick recap to catch you up on why this would be a wildly unexpected pairing: Blac Chyna, 27, is rapper Tyga’s ex ,and the two have a son together, King Cairo, 3. Blac Chyna was previously close pals with Kim Kardashian West, though the friendship appeared to fizzle after Tyga, 26, started dating Kardashian West’s sister Kylie Jenner, 18. Jenner and Tyga are still together, though they currently aren’t “on the best terms.”

Still with us? Blac Chyna is also best friends with Amber Rose, aka Kanye West’s ex, who got into a massive Twitter feud with Khloé Kardashian, 31, in February after Rose criticized Jenner and Tyga’s relationship, though she later apologized. Further complicating matters is the fact that Tyga and Blac Chyna aren’t the friendliest of exes – he lashed out at her on Instagram in September for allegedly spreading rumors that he couldn’t afford the Ferrari he bought Jenner for her 18th birthday in August.

Earlier today, Khloé Kardashian tweeted, “You can do anything. But never go against the family.”
