With all the posts they share on their social media accounts, you wouldn't think that Kendall and Kylie Jenner would be against Facebook, Instagram and Twitter. In fact, the reality television stars recently admitted that they "hate" social media and even call it a "made up world."

In an interview with The Sunday Times' Style magazine this week, Kylie even says that she's scared of getting older even though she's only 17-years-old.

"I'm scared of the day I turn 19," Kylie was quoted as saying. "I really don't want to grow past 18."

Kendall added, "It's scary. Life is scary. "It's just scary to think how fast everything is rolling and you can't stop it. It's rolling right now. You see a picture and you've changed so much in a year."

As far as social media, the sisters have nothing positive to say about it, despite the fact that they post several photos, messages and Snapchats a day to their fans.

"I think social media has taken over for our generation," The Sunday Times quoted Kendall as saying. "It's a big part of our lives and it's kind of sad."

"I hate it sometimes, like, I literally want to throw my phone so I can't look at it," she added. "It's all a made-up world if you think about it. Social media, everything, this interview, everything. It's not real. It's pretty crazy."
