• Kylie Jenner recently posted to Instagram to celebrate her daughter's one-month "birthday."
• The photos gave fans their first glimpse of Stormi's face.
• But many seemed to focus on Jenner's ring finger, which sports a ring that appears similar to a wedding band.
• This is not the first time the "Life of Kylie" star has sparked engagement rumors with her partner, Travis Scott.

Kylie Jenner has become a famed master of mystery. Since the confirmation of her secretive pregnancy, the new mom has been very selective about which personal details she shares with the world — particularly when it comes to her daughter, Stormi, and Stormi's father, Travis Scott.

Jenner recently posted two photos on Instagram celebrating Stormi's one-month "birthday," giving fans their first glimpse of the newborn's face.

"My angel baby is 1 month old today," Jenner wrote.

While many commenters offered congratulations and well wishes, others focused on the sparkly new accessory on Jenner's left ring finger.

"Omg is that a wedding ring? Am I hallucinating?" one comment read. 

"Can you see the ring ????" another person wrote.

Scott himself posted a simple comment that was not at all helpful for deciphering their relationship status.

Still, fans continued to speculate about their engagement on other social media platforms.

This is not the first time Jenner and Scott have sparked engagement rumors. The "Life of Kylie" star was wearing an identical ring in the first Instagram selfie she posted after giving birth. Commenters on that photo were similarly shrewd in their jewelry observations.

"KYLIE😍 AND THE RING??" one person wrote excitedly.

"YALL JUST IGNORING SHE GOT A RING ON HER FINGER," another commented.

It's worth noting that this ring is different from the diamonds she has flaunted in the past. In a scene from her pregnancy announcement video, the Kylie Cosmetics creator sports some noticeable bling. She tells the camera that she's at the eight-month mark — meaning it was filmed at the beginning of January.

Two months before that, Jenner posted a video on Snapchat as she drove to sister Kim Kardashian West's baby shower, in which she exhibits a massive sparkler on her left ring finger.

Jenner's current ring is markedly more subtle, like a wedding band rather than an engagement ring, which could indicate that she is already married. It's not the wildest theory, since it wouldn't be the first time she has shielded a major life event from the public eye.

Of course, this is all speculation. People magazine previously reported that the happy couple is in no rush to tie the knot. 

"There are no plans for them to get married or even engaged," the source told People in January.

Kardashian enthusiasts will undoubtedly continue to hypothesize about the reality star's personal life — but knowing Jenner, it's doubtful that she will confirm or deny anything soon. She seems to enjoy keeping fans in suspense.
