Just weeks after announcing their engagement, it appears Rob Kardashian and Blac Chyna have a baby on the way.

TMZ.com was the first to report the news Friday, saying the "Keeping Up With the Kardashians" brother and his model fiancée were planning to make a big baby announcement on Mother's Day.

Shortly after, both of them appeared to confirm the news by posting a photo on their respective Instagram accounts that looks like an emoji version of Chyna with a baby bump.

Kardashian, 29, and Chyna, 27, became engaged in April after about two months of dating. Chyna's ex-fiance, rapper Tyga, is dating the youngest Kardashian sister, Kylie.
