Kendall & Kylie Jenner Live The Luxe Life, Admit They've Had To Grow Up Quickly

Kendall and Kylie Jenner are not your average teenage girls, nor do they live average teenage lives.

Kendall, 17 and Kylie, 15 have grown up right before our eyes over the last seven seasons of "Keeping Up With The Kardashians," perhaps faster than most of their peers.

"I’m growing up and so is my little sister. We may be growing up a little faster than other people but we've had older sisters our entire lives who are in their 30s,” Kendall told radio hosts Scott and Todd on 95.5 PLJ Radio in New York City. "We are a little more mature than someone our age but I don’t think we’re growing up too fast in any way. We’ve had to grow up fast, just being in the public eye you kind of have to grow up fast.”

In addition to appearing on their family's reality series, both girls work as models and also have their own fashion line with PacSun. There is no doubt they work hard, but one has to wonder if it's too much too soon. After all, once one has matching Louis Vuitton luggage, Greek vacations on massive yachts, and a $125,000 Mercedes-Benz SUV, what is there to look forward to in life?
