Why Kris Jenner won't mess with Blac ChynaLos Angeles, July 10 (AZINS) Reality TV personality Kris Jenner won't mess with Blac Chyna as she knows the model is aware of the Kardashian family's darkest secrets.

Kris has to be careful if she wants to prevent Chyna from taking her grandchild Dream Kardashian away from her son Rob Kardashian, reported aceshowbiz.com.

"Kris definitely does not underestimate Chyna. Chyna also knows some of the family skeletons they don't want to get out. They consider her dangerous," a source told hollywoodlife.com.

"All the Kardashians/Jenners know she's capable of anything. They will protect Rob and Dream, but they have to be careful. She could make it very hard for Rob to see his daughter. Kris is horrified that Rob Kardashian and Blac Chyna are not once thinking about their child and all this nonsense will be online forever."

"She's been trying to reach Rob and Chyna to stop what they are doing to no avail. She hates that all of this drama is happening, it's making her ill," added the source.

Chyna is currently seeking a restraining order against Rob after he posted her nude photographs on social media.
