UPDATE: The first images of Dream Kardashian have officially arrived. Rob and Chyna (and Kris Jenner, Corey Gamble, and everyone else in the delivery room) used the joyous occasion to pull off a mid-childbirth edition of the Mannequin Challenge. 

Blac Chyna and Rob Kardashian have officially welcomed their first child together: a baby girl whom they have already named Dream. The baby was born on Thursday morning at 9:18AM PST (Nov. 10) at Cedars-Sinai Medical Center in L.A., reports TMZ, and she weighed in at 7 pounds, 5 ounces. According to TMZ, Chyna was prepared to give birth to the baby by C-section, though as of now, the method of delivery has not been confirmed. 

There was apparently a brief conflict between Rob and Chyna's team and the hospital, TMZ also reports, as the couple had wanted cameras with them in order to record the birth for a future TV special, and some of the footage they desired was reportedly in conflict with the hospital's regulations. 

Though they had their own team of cameras present for the birth, Rob and Chyna do not want anyone else photographing their baby, so they apparently also hired a security deal to join them at the hospital and protect them from the paparazzi. 

Congrats to Rob and Chyna on their new daughter!
