Speculation on whether Kylie Jenner is pregnant has finally been put to rest with the answer being "yes, she is," or more appropriately, "yes, she was" pregnant. Jenner's baby came to the world last week, and the reality star released details about it via a video she titled "To Our Daughter." But there's one detail that she may have intentionally missed: the baby's name.

Giving the baby a name is undeniably one of the most exciting things to do for a family. It is quite unlikely that Kylie or Travis, or even the Jenners have not thought of a name yet. So, it isn't surprising if Kylie is just trying to keep the name secret for now. After all, she did hide info about her pregnancy.

Of course, this doesn't stop fans from making their own speculations and trying to find hints that may point to Jenner's daughter's name. One common question fans ask is whether Kylie will continue the Jenners' family trend of girl names starting with the letter "K." Everyone knows that the names of the Jenner matriarch, Kris, and Kylie's sisters — Kendall, Khloe, Kim and Kourtney — all start with "K." According to Mirror.co.uk, "Krystal" is the most likely option, with "Kirsten" coming close. "Rose" and "Malibu" were also suggested.

However, there is not enough proof for the suggested names and there is not much connection between them and Kylie. If there is one speculation that has a certain connection and thus, a possibility of it being the actual name, it would be "Posie." Although it does not start with "K," it does make sense when one understands the context.

"Posie" may be short for "Mariposa," which could mean butterfly. Fans know that butterflies seem to mean a lot to Jenner. She has butterfly rings, matching ankle butterfly tattoos with boyfriend rapper Travis Scott, who apparently also has a song called "Butterfly Effect," per PEOPLE.com.

People found out about "Posie" from an Instagram post by Kris. It featured a "Posie K" limited edition for the second anniversary of her cosmetics. As for what the "K" means, it can be easily assumed that this is a reference to their names in the family.
