Rob Kardashian and Blac Chyna took a trip down memory lane on Wednesday.

The Keeping Up with the Kardashians star and his bride-to-be, who got engaged in April 2014 and are expecting their first baby this fall, revisited the moment that the couple met.

“Me and Rob, we actually met at Kendall’s sweet 16. It was Kendall’s, right? At Six Flags,” Chyna revealed in a Facebook Live video to fans of meeting Kardashian at his younger sister Kendall Jenner‘s 16th birthday.

“That’s right. Was that Kendall’s birthday?” the 29-year-old said to his fianceé of meeting each other at the Southern California amusement park.

Chyna, 28, told fans of looking back at the moment she and her now-fiancé first met one another, “The weirdest thing now like looking back at pictures, we was like winning prizes together and sitting on the ride like close to each other.”

“It was just like weird. It was funny how like …” Chyna stated before dad-to-be Kardashian finished her sentence.

“Everything just comes full circle,” he chimed in, and quipped, “Gotta love Six Flags.”

PEOPLE breaks down six more revelations from the couple’s Facebook Live below:

Kendall v. Kylie: Who would they trust more to babysit the baby?
Kendall and Kylie Jenner‘s babysitting skills came into question during the Facebook Live video. Asked who they would trust more to watch their child, Chyna laughed and responded, “I would say both.” Rob, on the other hand, jokingly said, “Okay, well I would choose neither of them. No, I’m kidding. Probably Kylie. I’ll probably let Kylie babysit.” Chyna, who is mother to Tyga’s three-year-old son King, said of Kylie babysitting, “She can babysit the baby and King at the same time.”

Who in the Kardashian family gives the most unsolicited parenting advice?
Fathers Kanye West and Scott Disick apparently like to pass on parenting advice to the couple! Asked who in the Kardashian family gives the most unsolicited parenting advice, Chyna responded, “Scott or Kanye.” Kardashian chimed in of Mason, Penelope, and Reign’s dad, “Probably Scott. That’s family, so Scott. Definitely Scott.”

Will they carry on the "K" name tradition?
Chyna’s son King already has the letter “K” as the first in his name, which begs the question: Will the engaged couple carry on the “K” name tradition? “Um, you guys have to stay tuned for that too. I’m not trying to give up no more details about the baby,” Chyna answered in the video, leaving the possibility up in the air. But the dad-to-be might have squashed the theories. “Probably not,” Kardashian responded.

Where was their first date?
“Khloé’s house. Drinking a lot of Hennessy,” Chyna said of her first date with Kardashian. “Our real first date, it was probably just you cooking,” he replied to his fianceé. “Yeah, just cooking. I invited him over and I cooked for him and that’s how I rode him in.

Will any of Rob’s sisters be on Rob & Chyna?
Keeping Up with the Kardashians fans will get to see more of the Kardashian and Jenner sisters on the couple’s upcoming E! reality show. Asked if any of his five sisters will make an appearance on the series, Kardashian responded, “Of course. They’re my family and my only friends, so they’ll definitely be on the show.”

What they would do if they weren’t famous
If the expectant parents weren’t the stars of their own reality show, they both revealed that they would be in the strip club. “If I wasn’t famous. Oh god, Rob. I don’t know. I would probably be working in the strip club. I’m just kidding,” Chyna stated in the video” but added, “I would probably be still in the strip club. I’m just keeping it real. I can’t do nothing else.” Kardashian supported his fianceé and said that he too would be there with her. “That’s alright. And I would probably be in the strip club also. I would definitely go and find Chyna and go to the strip club. Eat some food. They got the best food in the strip club,” Kardashian said.
