Everybody Out! Blac Chyna Has Major Hospital Meltdown

The birth of Rob Kardashian and Blac Chyna's daughter, Dream Kardashian, turned into a complete nightmare today for the newborn's reality star parents, RadarOnline.com has exclusively learned.

According to a source close to the Kardashian clan, shortly after Rob's sister, Kourtney, 37, and her three-time baby-daddy, Scott Disick, 32, arrived to meet their new niece, Rob, 29, "started freaking out and was sweaty and really worked up!"

"Blac was going through it because she just wanted to be left alone for five minutes with her daughter Dream and Rob," said the source, adding, "Both Rob and Blac were completely overwhelmed."

Dream Kardashian arrived at 9:18am via c-section at Cedars Sinai Hospital in L.A. today.

"Rob asked Kourtney for her help in getting the rest of the family out of there, including his mother Kris and her boyfriend Corey, because he just wanted to be alone with Blac and Dream," the insider told RadarOnline.com.

"Kourtney completely understood because she's been there, three times, and she knows how much drama the family can be when there is a new baby born."

As RadarOnline.com previously reported, the birth was filmed and will appear on next season's Rob & Chyna reality show.

"Kourtney actually has helped Rob a lot through the process," said the source, adding, "She was also the one to advise him and Blac about on-camera delivery, since she was the only one of the Kardashians to do that."
