Youth Troubles: Kylie Jenner on Aging: ‘I’m scared of the day I turn 19’

While many teenagers report they have a fear of spiders and sitting exams, Kylie and Kendall Jenner have confessed they are afraid of growing up.

The two sisters, who are the youngest of the Kardashian-Jenner crew, shared their thoughts on social media and aging with The Sunday Times this past weekend, and both girls said they have a phobia of growing older.

“I’m scared of the day I turn 19,” said Kylie, who is now 17. “I really don’t want to grow past 18.”

According to The Times, Kylie then turned to her older sister Kendall, 19, and said, “You’ll be 20 this year — that’s crazy. And any second you’ll be like, 21, 22, 23…”

Kylie and Kendall have been in the spotlight since Keeping Up with the Kardashian’s started airing in 2007, when they were just 10 and 12 years old.

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

“I’ve done so much, physically and whatever,” Kylie added.

The girls, who have a combined following of 50 million fans on Instagram, said they are not huge fans of social media, which is shocking, considering how often they post.

Ruby Warrington of The Times noted, “When I arrive at the LA photo studio in West Hollywood, Kendall and Kylie Jenner barely glance up from their phones.”

“I think social media has taken over our generation,” said Kendall. “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 continued. “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.”
