Kylie Jenner has been totally MIA ever since pregnancy rumors started swirling, which fans took as confirmation that she is, in fact, pregnant. Over the past few months, reports have stated that Kylie's absence from her usual stomping grounds (social media) is a choice she made so that she could enjoy her pregnancy—the first thing she's wanted to keep private in her entire, highly-publicized life.
But now, fans have another theory as to why she's being extremely private: Because her lips have deflated since many doctors won't give pregnant women lip fillers.
While fans think they've cracked the case of the disappearance of Kylie Jenner, they seem to be forgetting that Kylie appeared at the Kardashian Christmas party with lips as plump as ever.
So chances are Kylie really is just keeping things low key to enjoy her pregnancy stress-free.
