(Yahoo!) - Kendall Jenner's 18th birthday celebration was a true thrill.
While the "Keeping Up With the Kardashians" teen star's big day isn't until Nov. 3, she and her family descended upon Six Flags Magic Mountain in Valencia, California, on Tuesday for an epic celebration. The famous family had the famed theme park to themselves for an evening of fun. In other words, No lines, no walking, and all the rides on Apocalypse and The Riddler's Revenge they could want.
"We're here for Kendall's birthday party," big sis Kim said in a Keek video capturing some behind-the-scenes video of the private party. "We rented out Magic Mountain. No one else is in the entire theme park but us and the people there to greet us. No one is even working in the concession stands. And we get to drive instead of walk."
"This is what Kendall wanted and it's a nice surprise for her," she continued. "So happy birthday Kendall."
A second video posted by Kanye West's new fiancée was taken on a roller coaster and features a lot of screaming. (Consider yourself warned.)
Kim wasn't the only one doing camera work to capture Kendall's special day. Kris Jenner, who appeared to be prepared for a trip to the Arctic with that fur-covered hooded jacket, made nice with estranged husband Bruce Jenner for the family event. They took a selfie along with his sons Brody and Brandon.
"It was a perfect night at the Magic Mountain," Kris wrote in the Instagram pic, which she tagged "#happybirthdaykendall."
Brody posted some videos as well, including one of Kendall and Kylie on the SlingShot, which featured, yes, more screaming.
"Birthday fun with my beautiful little sister," he wrote on Instagram.
Khloé, who reunited with her estranged husband Lamar Odom at Kanye West's concert earlier this week, appeared to be flying solo for this event, but seemed to make some new friends. Furry ones. And in a photo of the Superman: Escape From Krypton ride, she noted, "Kendall runs this town today."
Justin Bieber pal Lil Twist was also there and tweeted:
Dope ass day with the fam.... Happy B Day Kendall!! Love!!— Lil Twist #TeamTwist (@LilTwist) October 30, 2013
As for the guest of honor, Kendall posted just one pic of the eerily empty theme park at night, writing, "All to ourselves."
No doubt it was a night to remember.
