Not so fast!
The Keeping Up With the Kardashians star showed off a stunning ring on Snapchat Thursday evening. But it's not an engagement ring that she's wearing, it's actually a promise ring from Tyga.
Kylie captioned the video, "If this is my promise ring I wanna know what my engagement ring gonna look like."
So while Kylie and Tyga are still going strong, it sounds like they're not engaged just yet!
Take a look at the E! News video above to see the ring and to find out the latest updates on the rest of the Kardashian family!
