Rob Kardashian Is Dating Tyga's Ex Blac Chyna

According to E!

[...] while Kardashian is currently working to get back in shape after gaining more than 100 pounds and getting diagnosed with diabetes, a source tells E! that there is "concern" his new girlfriend is "preying" on his weak state in order to get back at Jenner and Tyga.

When Chyna posted texts allegedly featuring Tyga saying he wanted to get back together, Jenner slammed them as false.
