Blac Chyna Is Pregnant! Rob Kardashian and Fiancee Expecting First Child Together

The 'Keeping Up With the Kardashians' star proposed last month and is now going to be a dad.

First comes love, then comes marriage, then comes a whole bunch of made-for-reality TV drama, and then comes a baby in a baby carriage.

Rob Kardashian and Blac Chyna may not be doing it in that exact order, but TMZ reports that the 29-year-old Keeping Up With the Kardashians star and his fiancée of one month are expecting their first child together.

The couple seemingly confirmed the news themselves when they Instagrammed a pregnant avatar of Chyna and tagged each other over her belly.

This will be Rob's first child and the 27-year-old model's second -- as you surely already know, she has a 3-year-old song, King, with Tyga. As you surely also know, Tyga is now dating Rob's younger sister, Kylie Jenner. Which makes the family tree very...complicated.

While Rob's sisters previously called their engagement "f**ked up," it seems the family has since come around to the new couple.

"Kylie is over the relationship," a source previously told ET. "It was tough for her in the beginning. But she sees how happy he is and all she wants is for him to be happy. The general consensus in the house is 'Praise Chyna! Don't go!' They finally got the brother they always knew back."
