Blac Chyna and the Kardashian clan just did the mannequin challenge... in the middle of childbirth

You've probably all seen the so-called #mannequinchallenge' by now: the latest viral craze sweeping social media. But you've never seen it quite like this.

The premise involves freezing in utter stillness while the camera films you. Not something that most would attempt while trying to give birth to another human.

But American model Blac Chyna and Rob Kardashian, decided to do just that. The birth of their daughter Dream seemed an entirely appropriate time for an Instagram video...

In the video, Blac Chyna is literally in the middle of giving birth - but totally still - watched over by concerned partner Rob.

Rob's mother and Kardashian matriarch "momager" Kris Jenner is present holding Blac's hand, along with her mother Tokyo Toni.

She 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.”

Other noteable #mannequinchallenge participants have been Hillary Clinton and team, Beyonce and her two former Destiny's Child companions,

But trust a Kardashian to one up the entire world in the ludicrous social media stakes.
