Watch video of Blac Chyna in the delivery room. [VIDEO]

Rob Kardashian did the “Mannequin Challenge” in the delivery room where fiancee Blac Chyna gave birth on Thursday to their first child, a girl named Dream Renee Kardashian. The reality star posted a 19-second video of Chyna “pushing,” Kardashian greeting the baby, Kris Jenner holding Chyna’s hand, Corey Gamble videotaping the “birth,” and others in the delivery room. He titled the video “Dream Team,” and hashtagged it “#MannequinChallenge.” See the Mannequin Challenge video below.

The Mannequin Challenge is the latest Internet fad, which has groups of people freeze themselves in place in a variety of different scenarios. Typically, the camera pans from one frozen person to the next. And the challenge can last up to a minute, as each “mannequin” strikes a pose.

As Gossip Cop reported, Kardashian and Chyna welcomed Dream earlier on Thursday. Not long afterwards, a number of family members shared their best wishes on Twitter. Khloe Kardashian wrote, “My new niece is absolutely stunning!! So thankful I was able to land in time to witness this miracle happen! Praise God!” And Kylie Jenner tweeted, “I can’t stop looking at her. @robkardashian @BLACCHYNA she’s so beyond beautiful, a dream.”

Shortly before Kardashian shared the Mannequin Challenge video of Dream’s birth, a photo was posted on Instagram of the little girl (below). Check out Kardashian’s Mannequin Challenge video below, featuring him, Chyna, Kris Jenner and Corey Gamble.
