Rob Kardashian and Blac Chyna are already engaged to be married. The two have been together for several months now and are expecting a child together. While most people know that Chyna's friendship with Kim Kardashian was the reason she met Rob, the story of their first meeting has not been revealed until the couple's recent Facebook Live session.

Chyna talked about the first time they met, saying: “We actually met at Kendall's Sweet 16. The weirdest thing looking back at it, we were winning prizes together and sitting on the ride close to each other. It was weird. It's funny like...”

Rob added, finishing Chyna's sentence: “Everything just comes full circle.”

The two also revealed where they went for their first date and said it was at Khloe Kardashian's house, where Rob used to live in with his older sister.

While it's nice to look back every now and then, the two also have a lot to look forward to, including their upcoming show on E! The teaser for the reality show has already been released, and it promises to give viewers a fun time.

One scene in the clip shows Chyna yelling, “Are you still texting b***hes?” to Rob on the phone. Another scene features Chyna asking Rob whether he's ready to be a father, to which Rob responded: “That's what I always wanted.”

The couple's relationship has been rather controversial. In addition to how fast they got together, there was also the issue of Rob's half-sister Kylie Jenner dating Chyna's former fiance, Tyga. At one point, it even seemed like Chyna and Jenner were having a feud.

However, things were apparently not as tense as people believed them to be. Jenner shocked fans when she posted photos of her and Chyna on Snapchat. One of the photos even bore the message: “When we've been best friends the whole time.”

Rob and Chyna went public with their relationship in Jan. 2016 when the Lashed owner took to Instagram to post a photo of the reality star's arm with the caption: “The beginning.”
