Kylie Jenner agrees with the rest of us...she grew up too fast!

The teen reality star posted this on her instagram and wrote "Dammit, Kylie!". When you really think about it, she's done it all at 17. Rapper boyfriend, plastic surgery, putting boobs and butt on display, already a successful business woman, has a mansion in Beverly Hills...the only thing that remains is probably a sex tape! :-)
