Well that was quick. Blac Chyna and Rob Kardashian continue to go full throttle with their relationship, after recently announcing their engagement, they've followed that up today with an even bigger (ha) announcement. Blac Chyna is pregnant.

The couple announced the pregnancy on Instagram, cause where else. Chyna used an emoji of her with a pregnant belly, and tagged Rob Kardashian on the belly. Looks like King Cairo is going to have a half brother, and I won't even try to figure out what this means for Tyga and Kylie Jenner, if anything (does this mean they are semi-related now or something??).

Take a look at the Instagram post below, and congrats to the engaged couple.
