After staying tight-lipped about her pregnancy rumours since they first sparked in late September, the baby of the Kardashian Krew - Kylie Jenner - has added fuel to the fire this weekend when she sported a hefty diamond rock on her ring finger at sister Kim's baby shower.

Ever the elusive tease, the 21-year-old Snapchatted herself cruising to her sister's party with the glistening ring plainly in sight on her left hand.

Unlike her subtle approach to dealing with the pregnancy rumours, it seems that Kylie definitely wanted her fans to see this new jaw-dropping addition to her jewellery collection.

In fact, we're surprised she didn't use the KiraKira app to give its sparkle an extra boost.

So, could it be? Could Kylie Jenner really be engaged to her rumoured baby daddy Travis Scott? Or is this all just an elaborate game?

This wouldn't be the first time one of our favourite Instragram obsessions have teased us with a sparkler on their ring finger.

It was only earlier this month that Jenner's pal Hailey Baldwin had fans wondering if her jewellery choices signified an engagement to rumoured BAE, singer Shawn Mendes.

While we'd love to imagine that there could be a Jenner-Scott wedding on the horizon, as her approach to revealing the potential news was so low-key, we don't want to get our hopes up.

Perhaps Kylie and Hailey's ring choices simply mark a new gift giving trend: why wait for a man to give you a diamond ring when you can simply buy one for yourself?

Looks like we might have to take a trip to Cartier, ladies!
