To celebrate Kendall Jenner’s upcoming 18th birthday, the Kardashian/Jenner clan rented out the entire Six Flags Magic Mountain in L.A. “No one’s even working in the concession stands,” big sis Kim bragged/complained in one of her videos posted to social media. Joining the famous family were Kim’s new besties Tyga and Blac Chyna, Chyna’s mom, Kylie’s beau Jaden Smith and a ton of Kendall’s friends. Check out some pics from their day in the gallery and video below!
