Another day, another Kylie pregnancy conspiracy theory. For what has felt like 15 months now, there has been non-stop speculation over whether the youngest Kardashian-Jenner member is pregnant or not — and the fact that she's been MIA for months has only added fuel to the fire. Fans are wondering: Is she really expecting, or is this the greatest publicity stunt known to man? For all we know, she can walk out tomorrow sans baby bump and be all, "What? I just needed a break." Which honestly, fair enough.

But as the months have ticked by, the conspiracy theories have intensified. From speculation over why Jenner didn't show up in Kim's Christmas card ("It's because she'd have to wear maternity jeans!") to wondering why her newest Blue Honey Palette has the word "blue" in it ("It's because she's having a boy!"), clues have been whizzing through the rumor mill. And now there's a new theory a-brewing.

When the Kardashian-Jenner clan released their first-ever Calvin Klein shoot, Jenner made an appearance clad in the brand's underthings just like her sisters. But people were quick to point out she wasn't baring her briefs like the rest of the fam, but rather she used a blanket to conspicuously cover her tummy. Or in another photos, she used a blanket burrito her whole body, which knowing the confident sisters isn't a photo move they usually reach for.

But that wasn't the only clue. People also pointed out that Jenner has lost her signature full pout, and the reason, they suspect, is because she can't get lip fillers while pregnant. Even Dr. Simon Ourian, the man behind Jenner's injectables, told Page Six back in September that he wouldn't give Jenner fillers while she was pregnant.

"I recommend that women stop getting lip fillers as soon as they learn they are pregnant," he said at the time. "No one knows the implications of lip fillers on pregnant patients since dermal fillers haven't been tested on pregnant women."

Jenner has been diligent in keeping up the lips that have launched a billion dollar makeup empire, and people have been wondering if that was why she was keeping out of the public eye, sharing this before the CK ad even dropped. If her lips were back to their early Keeping Up with the Kardashian days, that could possibly be bad for business. And thus a new conspiracy was born.

People have been taking to their keyboards and Twitter to share their find. Many thought the Calvin Klein photo made it super obvious Jenner was pregnant, leaving no doubt in some fans' minds.

Some pointed out that she stopped posting selfies on her social media accounts, and that wouldn't have to do with the fact that she was protecting her tummy, but because she didn't have her full lips.

On top of that, Kylie Cosmetics launched new lip colors along with the Blue Honey palette, and she hasn't modeled any of the shades as she is prone to do. That's another tip-off that her injections might have dissolved.

Others pointed out that no one should be surprised there's secrecy involved around her rumored pregnancy, especially considering she didn't confirm or deny the fact she got injectables until much later. She has a strong sense of privacy on certain topics, as she is entitled to.

While it might be fun to get together with other fans and speculate what one of America's reality show queens is up to, some people have taken speculation too far and suggested Jenner isn't showing her face because she was "unattractive" before injections. Many are also ridiculing her decision for getting injections in the first place, and how she now can't bare to make an appearance without them.

While speculation is fun, tearing women down for the decisions they make about their body is always wrong — whether that be with cosmetic surgery or with sharing their pregnancy.
