Rob Kardashian's on-and-off relationship with Blac Chyna had marked the headlines in the past few months, however, their not-so-silent feud has come back again, and it's definitely back for more. Kim Kardashian's younger sib feared about the American model's revenge after she dissed her ex-boyfriend, Tyga.

Since March 29, Blac Chyna had been on a Snapchat war against her former boyfriend, Tyga. Because of this, Rob Kardashian knew that once the entrepreneur "gets going, there's no stopping her." According to Hollywood Life, Kourtney's younger brother is scared as he knows that he will be the next to get dissed!

"Rob's terrified," a source stated. "The fact that Chyna could lash out and say such hard things about Tyga means that she could say the same if not worse about Rob!" The recent Snapchat feud of Blac Chyna against the "Ayo" hitmaker made him look like he fails to provide child support. However, Rob Kardashian doesn't believe this since his experience with King Cairo proved Tyga to be otherwise. In fact, the "Keeping Up With The Kardashians" star believes that he is not a bad father.

The same source also said that Blac Chyna is obviously going through something and that Rob Kardashian, on the other hand, is hoping that he is excluded from the model's Snapchat list.

Meanwhile, TMX reported about Blac Chyna's dismay since she thinks that Tyga and Rob Kardashian are ganging up on her. She said that the two are tag teaming to spread lies against her. Apparently, the Snapchat battle started when the model and the "Hookah" hitmaker had a misunderstanding and soon after, things went bitter.
