Rob Kardashian's fiancee is really showing.
Blac Chyna can't hide her baby bump in this outfit.
The 28-year-old model showcased her growing belly when she stepped out on Monday in Miami, Florida, wearing a tight, cut-out jumpsuit. Chyna chose the summer style for a casual, poolside lunch with friends at her hotel.

Just last week, Chyna wasn't showing much at all in the white jumpsuit she wore to celebrate her birthday with fiance, Rob Kardashian, at a gentleman's club in Miami.
The newly engaged couple have never looked happier after announcing their baby news, and Kardashian's step-parent, Caitlyn Jenner, recently told ET that she's proud of the 29-year-old reality star.
"You know, everybody goes through tough times in their life and deals with a lot of different things," Caitlyn, 66, said. "I always look at it as 'Everybody has their stuff,' you know? It's how you deal with your stuff, and how you come out the other end. Things are going well."
Kardashian's mother, Kris Jenner, is also "thrilled" for her only son. "Rob turned his life around and it’s all because of Blac Chyna," a source close to Kardashian shared. "She has brought him back to his old self and Rob is so excited to be a father."
