Kris Jenner is not allowing Blac Chyna and Rob Kardashian to start filming the second season of "Rob & Chyna". The couple is reportedly furious that Kris is pumping the brakes on the new season of their hit reality series.

"Kris is controlling everything," a source close to the family tells Radar Online, "It's all politics and it is bizarre. That show got huge ratings. 'KUWTK' is tanking in the ratings. It should be a no brainer for Kris, but it isn't."

Blac is holding out hope that her future mother-in-law will allow them to start filming again, according to the source. "Chyna signed a multi-year contract with E!. She is still under contract with them for both KUWTK and Rob & Chyna. She is ready to work," explains the source.

"The network wants to do it; Rob and Chyna want to do it but Kris won't let them start yet and she is coming up with every excuse in the book," continues the source, "Kris is being vindictive and exploiting Chyna. She's pitting the entire family against her. It's a vicious war against Chyna."

"When it comes down to money, Chyna brings it in. But Kris is in charge. And she isn't moving forward at all," the source concludes.
