Blac Chyna Shares Ultrasound Of Baby With Rob Kardashian: 'Fairytales Do Come True'

Pregnant Blac Chyna is on cloud nine, and she wants the world to know!

The model, who has gained 20 pounds in baby weight already, took to Instagram Monday night to share a new ultrasound photo of her new little one, including a sweet note to fiancé and father Rob and her three-year-old son, King.

"For a long time I felt like King was going to be an only child. That he was my greatest blessing and we were gonna live happily ever after together Just the 2 of us, I was no longer looking for love because I thought I had all that I needed. We needed," the 28-year-old wrote of her firstborn with ex Tyga.

"But look at God! Here I am Engaged to be married to one of the greatest men I know who loves King & I unconditionally AND having another bundle of joy! I just want to say Never give up & ALWAYS have faith because fairytales DO come True #LookAtOurLittleNugget #KingsGoingToBeABigBrother," she continued.

As RadarOnline.com readers know, Rob and Chyna announced their engagement just weeks ago, and no one was expecting a baby to be on board so soon — especially the Kardashian klan.

Now that she's joining the family, the exotic model has made the official move to change her name as well. On May 3, Blac Chyna — born Angela Renee White — filed to trademark her soon-to-be married name, Angela Renee Kardashian, with the United States Patent and Trademark Office.
