Most recently, Jenner, 20, stepped out in activewear looking a little fuller than usual.
One fan wrote: "You Can see she’s pregnant on This pic 😊".
While another commented: "Yes Kylie is pregnant and they will reveal the genders on there next episode."
Last month, Jenner reportedly threw herself a baby shower at her own home, here photos were taken of the backyard that was lit up with pink decorations.
She herself has still not confirmed the news in any way, so heck, she may not even be pregnant at all!
Perhaps fans will have to wait and see (on Keeping Up With the Kardashians of course).
