Could Kylie Jenner have given birth to her baby girl in secret?

Following rumors suggesting that one of her sisters may have accidentally shared a photo of Jenner's baby bump over the holidays, fans on Twitter have begun to suspect that the 20-year-old Keeping Up With the Kardashians star already welcomed her first child.

According to a report by Hollywood Life on Dec. 27, several Twitter users have been chatting about the odd theory in recent days.

"Omg what if Kylie Jenner already gave birth since Khole is 6 months," one person wrote.

As many Twitter users pointed out, rumors were swirling in regards to Jenner's pregnancy long before her older half-sister, Khloe Kardashian, began facing rumors of her own pregnancy. Kardashian recently confirmed that she is six months pregnant, so several people have assumed that Jenner is much further along if she hasn't given birth already.

Although a secret birth is slightly possible, it seems unlikely, considering that Jenner wasn't linked to her current boyfriend until this past April. Even if Jenner had gotten pregnant with Travis Scott's baby immediately after they started dating, she still wouldn't give birth until sometime next month.

While Jenner and Scott appeared to be going strong at first, they have been spending more and more time apart in recent months due to his ongoing tour schedule. Because of that, rumors have been swirling in regards to possible cheating and time with strippers.

Earlier this month, a source claimed Jenner was preparing to be a single mother as her boyfriend remained on tour.

"Kylie is starting to realize that she might be on her own with her baby that’s on the way and that is OK with her. When she first learned she was expecting Travis’ baby she had romantic fantasies about how wonderful Travis and she would be together throughout her pregnancy and then as parents," a source close to Jenner explained to Hollywood Life. "Now that Travis is simply not around that much, her reality isn’t matching her expectations and Kylie is coping with the real possibility that she may be a single mommy.”
