According to sources close to the couple, Kardashian proposed to Chyna on Monday night before hitting up a strip club together, TMZ reported.
The couple posted a couple photos on social media Tuesday of Chyna's large diamond ring.
"YES !...!...!" Chyna captioned an Instagram image of herself grabbing at a smiling Kardashian's face while her ring was in full view.
Kardashian shared a photo of Chyna on his own Instagram account in which she was rocking her huge ring while holding up a big stack of dollar bills.
The pair reportedly toasted their engagement with Chyna's mother at Ace of Diamonds strip club last night. But as for Kardashian's family, they were boarding a plane for a family vacation.
Chyna's friend Amber Rose also appeared to confirm their engagement on Instagram.
Rose wrote, "Congratulations to my Family @blacchyna and @robkardashian!!! Please don't let nothing or no one tear u guys apart! I never seen my sis so happy and I couldn't be more happy for her! Sometimes we find love in the strangest places. Lol God Bless you 2! Now let's get this wedding together so y'all can start making some babies. #TrueLove #putaringonitsouknowitsreal #BlacRob."
Kardashian and Chyna first went public with their romance in January. Reports circulated at the time his family was livid, especially because Chyna has a son with Kylie Jenner's current boyfriend Tyga. However, they seem to be coming around since Kardashian is finally happy and seemingly comfortable in his own skin again.
