Less than a week after announcing her pregnancy, Blac Chyna's baby bump walked the red carpet for the first time on Tuesday at the launch party for her new emojis titled Chymojis.

In a surprising move, the 27-year-old, who was accompanied by fiancé Rob Kardashian, traded her signature skin-tight dress for a flowy coverup with cutouts on the side.

Though the loose nature of the fabric masked most of her belly, the mother-of-one did cradle her bump several times while posing for photos.

Chyna and Rob fittingly revealed they were expecting on May 6 with a Chymoji of the model sporting an enlarged belly. Though the pregnancy may come as a shock to some fans, the duo did get engaged only 10 weeks after first going public with their relationship.
