Just one month after announcing that he and girlfriend Blac Chyna are engaged to be married, the Keeping Up with the Kardashians star took to Instagram to announce that the pair is expecting their first child together. Kardashian shared a photo of an animated Chyna sporting quite the large bump. He captioned the photo with a bride emoji and a baby emoji. His fiancé posted the same photo, tagging him as her belly and captioning it with the baby emoji and the partying emoji. How's that for an announcement? Chyna's rep also confirmed the news to People, saying that the model is happy.
