Apart from "KUWTK", the 28-year-old model will also be seen in her own reality show with her husband-to-be. The six 60-minute episode docu-series, titled "Rob & Chyna," will cover the couple's daily lives and is likely to end with their child's birth. The show is set to debut later this year.

Chyna announced her pregnancy in May. A source told Us Weekly that she is due in October. She has yet to reveal the gender of the child.

The mother-to-be was recently spotted glowing in a baby blue dress in Los Angeles. She showed off her growing baby bump in the form-fitting knee-length outfit which she paired with comfortable flats and diamond accessories, including her 7-carat engagement ring, People reported.

Rob, 29, and Chyna, who has a three-year-old son, King Cairo, with her former fiance Tyga, caused controversy when they first started dating as she had been feuding with his sister Kylie Jenner and Khloe for some time. The news of Chyna's pregnancy caused quite the storm on the family's reality show, with recent episodes showing how upset the sisters were that Rob had not told them in person but made the announcement on social media.

In the recently aired episode, Khloe particularly appeared devastated when Rob broke the pregnancy news in front of his sisters. While both Kourtney and Kim Kardashian told him how happy they were, Khloe seemingly was unable to hide her emotions as she silently kept her head down and sulked for the rest of the siblings' meeting.

Meanwhile, Chyna took to Instagram to share an intimate pic in which Rob is seen hugging her bare baby bump. She appears to be wearing nothing but lace red underwear.
