It's not funny to her!

Kylie Jenner is furious that someone created a video that made it look like her baby daddy Travis Scott was caught cheating, and she's not taking the viral prank lightly.

"Idk if this is really a social experiment to some people but you’re messing with real people, real relationships, real family. I’m happy my relationship is strong because this is getting out of hand. The internet scares me sometimes for real," she said on her Instagram stories.

Her sisters are outraged, too!

"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!” Kim tweeted.

"People are absolutely disgusting! The mind games this would do to somebody… That is so completely not OK! This person should be so ashamed of themselves! What filth," Khloe added.

YouTuber Christian Adam admitted to staging the pic to trick everyone, but not before letting the rumors run wild for a while.

"That photo that you see of Travis Scott allegedly cheating on his significant other Kylie Jenner was completely staged. The goal of this video is not to hurt anybody’s relationship, but it’s to see how gullible is the internet," he tried to explain.
