The "Keeping Up With the Kardashians" star and Chyna, whose real name is Angela White, announced the news on Instagram Friday by posting an image of a digital Chyna cradling a baby bump.
A rep for the couple later confirmed the news to ABC News.
Kardashian and Chyna's romance hasn't been an easy one since the two came out as a couple earlier this year. They were engaged months later.
Chyna dated rapper Tyga starting back in 2011. The two have a son, King Cairo, who is 3 years old. The rapper has since dated Kylie Jenner, Kardashian's sister.
