Kylie Jenner knows how to throw an epic birthday celebration. The 20-year-old reality star [1], who welcomed daughter Stormi Webster [2] with rapper boyfriend Travis Scott [3] in February, rented out Six Flags Magic Mountain on Saturday for his 26th birthday. "They've never been," she captioned one Instagram video of her "baby" and his friends on a ride.

There was also a theme-park inspired cake featuring animations of Kylie, Travis, and baby Stormi [4] to cap off the occasion. Keep reading to see more photos from Travis's fun birthday bash.
