Kylie Jenner's ring mystery solved: She's not engaged to Tyga!

Tyga may have put a ring on it- but that doesn't mean that he and Kylie Jenner are planning to get hitched.

Kylie Jenner has been walking around with a pretty mean rock lately. The type that is sure to spark engagement rumours.

But if the Keeping Up with the Kardashians star is to be believed, the bling on her finger is just a promise ring from her bae.

Kylie took to Snapchat on Thursday to post a snap of herself wearing a HUGE diamond ring, next to a caption labelling it a "promise ring".

Girl, we've seen promise rings and they hardly ever come that big and that flashy!

It seems Kylie also has high expectations for her engagement ring- should the couple's turbulent relationship ever get to that point- saying that she can't wait to see how Tyga will upgrade her.

The rapper better start saving.

At least his bank balance is looking a little fresher, following the news that he signed with Kanye West's G.O.O.D record label this week.
