LOS ANGELES — Rob Kardashian, 29, and fiancee Black Chyna, 28, are expecting a baby girl.
On the premiere episode of the couple's E! reality show, "Rob & Chyna," the sex of their baby was revealed.
The announcement on the show was met with excitement on social media from Kardashian's sisters, Kim and Khloe, and matriarch Kris Jenner.
The couple has had a whirlwind romance. The couple got engaged less than three months after confiming they were dating.
The engagement and baby mean the Kardashian-Jenner family will have an interesting family makeup, to say the least.
Chyna, once close to Kim Kardashian, attended her wedding to Kanye West in Italy. At the time, Chyna was engaged to rapper Tyga, who has an on-again, off-again and currently on relationship with Kim and Rob Kardashian's younger half-sister, Kylie Jenner.
Chyna and Tyga have a 3-year-old son together, King Cairo Stevenson. With a baby on the way and the "promise ring" that Tyga gave to Jenner, King Cairo would be both a cousin and a half-brother to Kardashian's and Chyna's baby girl.
