Kylie Jenner celebrated in advance Travis Scott's 26th birthday by being all out, renting a whole Six Flags theme park all to themselves.

The makeup maven definitely knows how to throw a fun-filled birthday surprise for her beau. Jenner shared to her more than 107 million followers just how much she was willing to go the extra mile for her baby daddy, rapper Scott, even if it meant going for the untraditional theme park celebration instead of the overflowing booze party.

"Rented out Six Flags for baby's birthday. They've never been," Jenner wrote.

The 20-year-old social media superstar uploaded a series of photos and videos on her Instagram Stories that showed their high time at the amusement park. Also present during the celebration were Kylie's sisters, Kendall, and Kim and Kourtney Kardashian. Rapper Kanye West and the Kylie Cosmetics owner's close friend, Jordyn Woods, were spotted as well.

Adorable Cake

Technically, Scott won't be 26 until April 30, but he already had a birthday cake taken care of his loving girlfriend, Jenner, on April 28 during their time at the Six Flags Magic Mountain in Los Angeles. Renting out the whole place might be the best move for all of them, as most of the attendees were prone to get media attention.

It's not only that, Jenner had the place transformed into looking like Astroworld, a theme park in Texas that stopped operations in 2005 and also where Scott used to visit as a child. Coincidentally, it is also the name of his album.

The cake was in line with the theme and very apt and timely as well, so props to Jenner for that. The rollercoaster cake showed riders that looked like the model, Scott, and their daughter, Stormi, at the Astroworld.

Jenner pointed out that she specifically asked for the Stormi image on the cake to have a seatbelt. Understandably, their bundle of joy wasn't in the theme park for daddy's birthday celebration.

Attendees seemed to have enjoyed the rides and some private time off parenting duties. Most of the guests wore a customized sweatshirt that had Scott's birthdate on it. It also had the word "Texas" on it. Clearly, everything was prepared for the "Goosebumps" singer, who was revealed to have never been at the Six Flags before.

This isn't the first time the Kardashian-Jenner clan enjoyed some time at the amusement park. The Six Flags was also rented by the family during Kendall's 18th birthday in 2013.
