Just hours after Blac Chyna and Rob Kardashian revealed that they are expecting their first child together, the 27-year-old was seen driving around Los Angeles with a friend of hers. The two parents-to-be shared the news within minutes of each other via Instagram, using an emoji of Blac rubbing her baby bump. Rob and Blac began dating in late January of this year and announced that they were engaged back in early April. Blac shared the first photo of her ring, writing, "YES!...!...!" Rob, 29, later shared a picture of his bride-to-be flashing her rock while holding a stack of dollar bills.
