Tyga’s EX Blac Chyna is reportedly PREYING on Rob Kardashian

As we all know, Rob Kardashian has been quite vulnerable over the past few years, and according to insiders, TMZ is reporting that Blac Chyna is taking full advantage of it.

Sources close to Rob told the website that because he's dealing with so much now – his weight and recent diabetes disgnosis – Blac made her move because his guard is down. 

It was also reported that the picture Blac posted on Instagram yesterday is of Rob holding her, and she captioned the image, "the beginning."

TMZ sources also say Rob's friends think the fact Chyna's BFF Amber Rose just started following Scott Disick on IG is more proof this is a full-on "attack."
