Calabasas, California - Fans suspect that Kylie Jenner may have given birth to her second baby - and it's all thanks to her social media silence and a clue Travis Barker unintentionally shared.

On Sunday, Kylie's soon-to-be brother-in-law Travis shared a pic that featured a random milk-filled baby bottle.

The bottle in question sat in the corner of his snap of the family's How the Grinch Stole Christmas movie night on his Instagram story.

Since Travis and Kourtney Kardashian haven't made any pregnancy announcements, many assumed that the bottle may belong to the 24-year-old billionaire. It has led to widespread speculation that Kylie has once again secretly given birth.

One user took a screenshot of the mysterious item, captioning the reposted pic, "Hi @travisbarker you can’t just post a pic of a baby bottle and be like, 'Imma just leave this here.'"

Other commenters jumped in and agreed that the bottle must belong to Kylie's supposed newborn, since she's the only Kar-Jenner member confirmed to be expecting.

"Kylie used those exact bottles when Stormi was little," one person noted.

Yet if the beauty mogul did give birth, she probably won't confirm it right away, since she and partner Travis Scott have been keeping a low profile following the tragedy that occurred at the rapper's AstroWorld concert last month.

The horrific incident claimed the lives of 10 people in a crowd surge and left hundreds of attendees injured, resulting in multiple open lawsuits against Scott.

The couple have both received significant backlash over the incident, although the Sicko Mode rapper more so – who has reportedly denied responsibility and claimed he was unaware of what was happening in the moment.

On Christmas Eve, the Kylie's Cosmetics owner made a brief reappearance on IG by sharing a photo from her mom Kris Jenner's rendition of Jingle Bells.

Unfortunately, some users took the opportunity to slam her in the comments section.

Will Kylie continue to keep her life offline, and her lips sealed on whether her latest bundle of joy has arrived?
