Most teenagers celebrate by going to Disneyland or something, but not this famous family!

Kylie Jenner has finally graduated high school, and the reality star was thrown a lavish surprise bash to commemorate the big achievement by none other than Ryan Seacrest! Held at Kris Jenner's house, the soiree looked wild in typical Kardashian fashion, and the 17-year-old captured some of the crazy moments in a series of Snapchat videos!

The party was also for older sister Kendall, who graduated last year, but who cares about the youngest Jenners when Khloe is twerking! Lamar Odom's ex showed off some impressive sexual dance moves, and her booty looked insane!

Not to be outdone, Tyga's girlfriend decided to grind on Kenny in another clip, and it just makes us uncomfortable! Giving your sibling a lap dance is more than a little awkward!

She's still acting way older than she actually is, but at least now she's not a dropout! You have to watch the below Snapchat video montage!
