The youngest of the Kardashian/Jenner clan at 18, she shared a photo of a VERY large diamond ring on Christmas Day.
Merry Christmas pic.twitter.com/6LaAKl19V1— Kylie Jenner (@KylieJenner) December 26, 2015
Posting the photo of the ring on her hand to her 13million Twitter followers, she simply wrote "Merry Christmas" alongside a heart emoticon.
Of course, the picture sent the rumour mill into overdrive as her followers jumped to a natural conclusion... That boyfriend Tyga has popped the big question.
Although it's the wrong hand for an engagement ring, it wouldn't be the first time the family had kept us guessing!
One fan wrote: "Why would someone buy a ring like that and not get engaged?"
Another joked: "My entire college tuition and more all on her single finger."
Yep, it looks like the MOTHER of all rocks... Either way, Kylie is one lucky girl...
On Kylie's 18th birthday, Tyga gifted her a Ferrari worth $320,000, so the teenager is certainly used to expensive toys!
Kylie also shared a snap from the Kardashian's famous Christmas Eve party at Hidden Hills, where she looks stunning in a green goddess frock alongside her MILF mum.
Kylie and Tyga were rumoured to have split up last month during a rocky patch, but are clearly back on track.
During an appearance on Ellen in November, Kylie said: "We're not broken up. We just ... honestly. We became best friends before anything happened, so I think that's awesome and we're just like, I don't know, hanging out. Living life."
Kylie and Tyga, 26, went public with their relationship around her 18th birthday in August. She then starred in his music video for '$timulated', where she was filmed making out with the musician.
In September, rapper Tyga called Kylie his "fiancee" in a Snapchat video.
