Blac Chyna and Rob Kardashian are reportedly expecting their first child together. On Friday, the 27-year-old announced that she is pregnant with her second child, just weeks after revealing she was engaged to Kardashian. The parents-to-be shared the news within minutes of each other on Instagram, using an emoji of Chyna rubbing her baby bump. Rob and his fiancée have been dating since January, and it's safe to say it's been a whirlwind romance ever since they first stepped out on the town.
