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 [sic] next episode."
Last month, Jenner reportedly threw herself a baby shower at her own home, where photos were taken of the backyard lit up with pink decorations.
She 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).
