• Many Kardashian fans believe the family will announce Kylie Jenner and Khloe Kardashian's reported pregnancies on their holiday card. 
• Writer Mariah Smith sparked a discussion around this theory on Twitter. 
• Others believe that Kylie and Khloe will reveal their potential news in the 25-part card, which is being unveiled one photo per day over social media.
• An unnamed source told Hollywood Life in October that Kris Jenner wanted to make the news official in the card.

It's been over two months since reports surfaced alleging that Kylie Jenner and Khloe Kardashian are pregnant. Both Kylie and Khloe have remained silent about the reports, and "Keeping Up With the Kardashians" has kept fans watching in suspense by dropping potential hints without revealing anything concrete.

The wait for confirmation may soon be over, however. That's according to a popular theory that says the family is planning to announce Kylie and Khloe's potential pregnancies on their "25 days of Christmas" holiday card.

Writer Mariah Smith sparked a discussion around this theory on December 3 when she tweeted: "The Kardashian's 25 days of Christmas/Christmas card reveal will most likely serve as our Khloe/Kylie pregnancy announcement."

After being asked when the pregnancies would potentially be announced, Smith — a self-proclaimed "Kardashian truther" who covers the show for The Cut's Keeping Up With the Kontinuity Errors column — tweeted that the reveal is likely to happen near Christmas.

Other people are also convinced that a holiday card announcement is forthcoming.

It's unclear exactly where the theory started, but a source told Hollywood Life in October that Khloe and Kardashian's pregnancies would be revealed in the family's holiday card. 

"The Kardashian Christmas card is something that is very important for Kris Jenner," the unnamed source exclusively told Hollywood Life. "Kris wants to take everyone's excitement and use this year's card to be the reveal of all the pregnancies in the family."

Up until now, the 25-part holiday card has shown us glimpses of the Kardashian-Jenner family in surprisingly casual outfits — all denim and white basics — amid a white background. Each picture, taken by the photographer Eli Russell Linnetz, highlights a few family members in an artistic way, with some people cropped out of the frame.

As Kim Kardashian West told James Corden on "The Late Late Show," this year's card is limited to the women and kids in the family — which seems like a fitting way to announce any potential baby news. Kylie and Khloe haven't yet appeared in the holiday card, so we'll be keeping our eyes peeled. To keep track, check our story on every single photo in the Kardashians' holiday card here.
