The Keeping Up with the Kardashians star shared a throwback photo on Friday documenting the early days of friendship between the 29-year-old and his now fiancée.
In the hilarious picture shared on Instagram, Kardashian, Chyna and Kim Kardashian West are seen enjoying the Tatsu roller coaster at Six Flags Magic Mountain in Santa Clarita, California in 2013.
“#throwback from 2013 Six Flags ,,, look at our faces lol. me with @blacchyna and @kimkardashian,” Kardashian captioned the photo with three blue emoji hearts.
“Me and Rob, we actually met at Kendall’s sweet 16. It was Kendall’s, right? At Six Flags,” Chyna recalled.
“That’s right. Was that Kendall’s birthday?” Kardashian said to his fiancée of meeting each other at the 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.”
