If this is true, we are seriously at a loss for words!

Blac Chyna just posted an Instagram photo of herself with a tattooed male arm wrapped around her, and it's obvious from the ink that it's Rob Kardashian! The former stripper seems to be hinting that she's hooking up with Kimmy's brother, which isn't going to go over well with Kylie Jenner and Tyga.

In case you haven't been following the love triangle, Blac dated and had a kid with Tyga before he moved on with Kylie. The barely legal plastic surgery princess and the single mom have let their feud play out on social media, and the Kardashian clan has done everything in their power to make her go away. It doesn't help that she's now best friends with Amber Rose, who was Kanye's girlfriend before he got together with Kim.

Basically, Rob is boning a chick that used to bone his baby sister's boyfriend. Gross! It's time for Kris Jenner to intervene and put a stop to this!
