Engaged — and now expecting.

Rob Kardashian and his fiancée Blac Chyna are expecting a baby together, her rep confirms to PEOPLE.

“I can confirm she’s pregnant and of course she’s happy,” the rep tells PEOPLE.

Both Kardashian, 29, and Chyna, 28, took to Instagram on Friday, sharing an emoji rendering of a pregnant Chyna. Alongside her post, the mom-to-be added baby and party emojis while Kardashian opted for baby and bride emojis.

Chyna’s ex Tyga commented on her Instagram post, writing “Congratulations.”

This is the first child for Kardashian and the second for Chyna, who shares 3-year old son King Cairo with TygaKardashian’s sister Kylie Jenner‘s boyfriend.

It’s been a whirlwind romance for the couple, who were engaged 10 weeks after going public with their relationship. But since news broke of their romance, Kardashian and Chyna haven’t been shy about sharing their love for each other on social media — or showing off the 7-carat diamond ring he used to propose.

Although the couple have yet to set a date to tie the knot, sources told PEOPLE that they are “definitely looking to tape their wedding.” And in between all the wedding prep, Kardashian and Chyna were already planning their future family together.

“[They] are talking about babies too,” a source previously told PEOPLE. “They both seem very excited.”

Kardashian may have a hard time coming up with a push present to top his recent gift for his bride-to-be. In April, the youngest Kardashian bought Chyna a purple Lamborghini as an early birthday present.

“Thank you baby for my Huracan Lamborghini,” she captioned a picture of the two posing alongside the sports car.

TMZ was first to report the news.
