Another Kylie Jenner Snapchat, another bit of fodder for the pregnancy rumor mill. Between baby-colored phone cases and suggestive song lyrics, the 20-year-old has been teasing fans with possible clues via Snapchat for weeks now. But some fans are speculating that the Life of Kylie star’s accessory in her most recent snap could be the most convincing bit of evidence yet.

The Kylie Cosmetics founder posted a video of herself with a bunny filter sitting in an empty jet. The Keeping Up With the Kardashians star says, “I’m on this plane all by myself.” She’s looking comfy in a gray pullover and — wait for it — what appears to be a baby block necklace. *Cue alarm bells*

What’s more, the blocks spell “Cactus Jack,” the name of boyfriend and supposed baby daddy Travis Scott’s record label. Internet sleuths are taking it as a sign that the necklace was a gift to Jenner from the rapper. She still hasn’t publicly addressed the swirling pregnancy rumors.

And not to get into semantics or anything, but if the youngest member of America’s first reality show fam really is the “only one on the plane,” who’s flying?
