Blac Chyna does the Mannequin Challenge from the delivery room - with Kris Jenner

It's going to be hard to top Blac Chyna's Mannequin Challenge.

Joining the social media craze, the 28-year-old Rob & Chyna reality star filmed her freeze-frame moment from the hospital delivery room where her baby daughter, Dream Renee, entered the world.

The hilarious clip, captioned "Dream Tream", Blac pretends to be mid-childbirth surrounded by her fiancé Rob Kardashian, and his momager Kris Jenner and her partner Corey Gamble.

If you ask us, Kris Jenner's facial expression wins the whole thing.

"I got to watch [the] delivery," Kris, 61, told E! News. "It was so beautiful and I'm so excited and happy to have another grandchild! It was one of the most precious moments of my life."

Blac's mother Tokyo Toni was also on hand for the Kardashian baby arrival, via C-section.

Hang on, Kris was watching a C-section? Does that make it a K-section?

E! also dropped the first picture of baby Dream, who is already living the American dream (of social media fame). Meet her here:
