Kylie Jenner may be pregnant, but the Nude Pictures the reality star just shared online certainly do not show it --- and for a good reason.

This week, the 20-year-old star of "Keeping Up with the Kardashians" shared some racy snaps that included herself in the nude but strategically covered with a white towel. Kylie Jenner's nude pictures have generated quite a bit of interest, garnering news coverage across the internet but also sparking speculation about whether she is truly pregnant.

In the pictures, Kylie Jenner covered her midsection but some commenters noted that she does not appear to be showing any kind of baby bump, and certainly not the size they would have expected if she were indeed a few months pregnant.

But Kylie had an explanation --- the photos were actually from a while ago.

"I was going through some old photos from the past few years and found so many good Polaroids. I just had to share them exclusively with my app subscribers!" Jenner wrote.

Is Kylie really pregnant?

It was several weeks ago that news outlets reported Kylie Jenner was expecting her first child with boyfriend Travis Scott, but the reality television star still has not spoken officially on the matter. Kylie has kept her midsection covered in other pictures, including one where she had an oversized sweater during a game with her family. There could be some behind-the-scenes drama complicating matters.

A new report from Hollywood Life noted that Travis and Kylie may be on shaky ground, with Kylie [VIDEO] demanding that her boyfriend move in with her ahead of their baby's birth. It's not clear how much truth there is to the Kardashian drama, as the family is a hotbed for rumors especially when it comes to their relationships, with many of the reports turning out to be false.

Kylie Jenner's pregnancy could soon be revealed

As Hollywood Life noted, Kylie's is one of three pregnancies in the extended Kardashian clan. Sister Khloe Kardashian is reportedly pregnant as well and Kim Kardashian and Kanye West are awaiting their third child, being carried by a surrogate. There has been little revealed about these pregnancies, and that could be by design, the report noted.

'"Both Khloe [Kardashian] and Kylie will be revealing their pregnancies on the "Keeping Up with the Kardashians" mid-season finale," a source told the celebrity news outlet, adding that E! will be teasing the pregnancy reveals in the week before the episode hits the air.
