Ready for your first look at Baby Kardashian? Look no further than Blac Chyna 's Instagram account.The mama-to-be, who is expecting a child with Rob Kardashian , shared her sonogram on social media late last night. Clearly, it was an emotional moment for the star, who also has a son, King, with her ex Tyga."For a long time I felt like King was going to be an only child," Chyna wrote. "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. 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."
