Blac Chyna's baby bump on display with fiance Rob Kardashian

She only recently announced she's expecting a child with fiance Rob Kardashian but already Blac Chyna's baby bump is growing fast. The pregnant 28-year-old was seen out in Beverly Hills with Rob, after flying back to LA from New York where the couple lived it up at Sin City night club. And the former exotic dancer appeared to be feeling a little back pain as she walked through a parking garage with one hand pressed up against her spine after exiting her luxury sports car. Chyna, who already has a son King Cairo, three, with ex Tyga, covered her curves in the gray athletic gear that featured black stripes down each leg and black panels on the top.

She wore a matching gray baseball cap over her long raven hair and carried a fancy white and gold designer purse. Chyna did the driving for the couple's outing in the purple Lamborghini Rob gifted her soon after their engagement. It was in addition to the very large $325,000 diamond ring he proposed with in April. The pair have been dating since January.
