Grand-Momager Wars! Kris In Bitter Battle With Tokyo Toni Over Baby Dream

Delivery room videos from the birth of Dream Kardashian showed grandmas Kris Jenner and Tokyo Toni looking on with love, but RadarOnline.com has learned that their peace pact was short-lived!

"After Dream was born, Kris said some really nasty things to Blac Chyna's mom that really hurt her feelings," a source close to the family told RadarOnline.com.

As RadarOnline.com reported, Jenner, 61, and Tokyo Toni, 47, were on hand to witness the birth, which was all filmed for an episode on next season's Rob & Chyna reality show.

"But not only did Kris tell the crew to film Tokyo as little as possible, she also suggested that Tokyo Toni get her hair and make-up redone because it was not up to par with television standards!" said the insider.

As tensions rose, Blac Chyna and new baby daddy Rob Kardashian asked both women to leave, as RadarOnline.com reported. And Kris soon apologized.

"Kris was just really stressed out and told Rob and Blac that she did not mean to hurt Tokyo's feelings," the source added.

Now, "Rob and Chyna just want both of their mothers to cool it for a minute. Kris and Tokyo are acting like Dream is their child, and Rob and Chyna told both of them to just give them space for a couple of days, which they have," the source told RadarOnline.com.

"Tokyo does not think she will ever be able to be in the same space for too long with Kris though and for good reason!"

"Kris is all about her money and her riches and that is not how Tokyo lives. Kris just always seems to make her feel insecure, and that is probably not going to change."
