Though their union initially raised eyebrows due to Chyna’s complicated history with the Kardashian-Jenner family (she shares a son with Rob’s sister’s boyfriend, Tyga), the two shared quite a bit of affection on social media since hooking in January 2016.

​

Kardashian, 29, proposed to Chyna, 28 last spring and a month later, announced they were expecting their first child together. The two welcomed their daughter, Dream in November.

​

The couple has publicly experienced their fair share of ups and downs, especially on their E! reality show, Rob & Chyna. Much of their fighting was documented on the show, including screaming matches, therapy sessions and even a paternity test.

​

Earlier this month, Chyna stepped out with a mystery man in Los Angeles, fueling rumors that Kardashian and Chyna were no longer a pair.

​

PEOPLE reports that in happier times, Kardashian said that Chyna got him through his “darkest times.”

“I’ve been friends with Chyna for a long time,” he said in August. “She was someone I reached out to for advice. She would cook for me and we’d just talk. She’s surrounded me with a lot of positivity. From the moment we met, I knew I wanted to be more than friends.”
