Taking to Instagram Stories, Jenner responded to the prank, writing: "Idk if this is really a social experiment to some people but you're messing with real people, real relationships, real family," she wrote. "I'm happy my relationship is strong because this is getting out of hand. The internet scares me sometimes for real."
Her older sisters, Kim Kardashian and Khloe Kardashian, also responded with Kim writing on Twitter: "I hate that I am bringing attention to this but this is absolutely disgusting that you would find this funny to mess with Travis & Kylie who just started a family together. This is really damaging to relationships, families and is just so wrong!"
"People are absolutely disgusting! The mind games this would do to somebody… That is so completely not OK!" Khloe replied to Kim's tweet. "This person should be so ashamed of themselves! What filth."
