Another Kardashian is on the way. Who would have seen this coming!?

Rob Kardashian is about is about to become a father with his fiance Blac Chyna, her rep confirms to Us Weekly.

"She's very happy," says the spokesperson.

Multiple reports indicate that Chyna is several months along. TMZ reported that she was planning to make a big announcement on Mother's Day, but the website may have stolen the couple's thunder by breaking the news on May 6.

On Friday, the couple posted an emoji of a pregnant Chyna (think Kim Kardashian West's emoji line) to their respective Instagram pages winking at the pregnancy news.

It will be interesting to know how his family feels about the pregnancy, as they were less than thrilled about his engagement.

For Rob, it will be his first child. Chyna is already a mother to 3-year-old King Cairo, whom she shares with Tyga, who dates Rob's half-sister Kylie Jenner. (Should make for one heck of a family reunion!)

A baby is a bit of a shock to many, but Rob has certainly moved fast with this relationship.

The couple was rumored to have started dating in late January, much to the chagrin of his family, particularly Khloe Kardashian, who have seen Chyna as a thorn in their side. Two months into the romance, Rob proposed to his girlfriend with a $325,000 7-carat diamond ring.

He later bought Chyna a purple Ferrari, as well.

The pregnancy reveal comes at the end of a week that started out horribly for the model. Last weekend, Chyna's home was broken into and the thieves left with $200,000 in cash and a haul of jewelry.

There was no sign of forced entry and a safe containing the money wasn't busted open, leading police to think that someone close to the couple is responsible.

Rob and Chyna: Keeping news outlets on their toes since, well, 2016.
