Kris Jenner isn't a regular mom, she's a cool mom.

Blac Chyna opens up about her relationship with Rob Kardashian's mom on this Sunday's Rob & Chyna Baby Special. On the show, Chyna gets a 4D sonogram of baby Dream Kardashian and decides to FaceTime Kris to show her the cute photo.

"Everybody always talks about mother-in-laws and how they can be," Chyna says in the exclusive clip above. "But Kris is totally different, you know always willing to give me personal, good advice."
