Inside Kendall & Kylie's Surprise Graduation Bash

Wait, Kendall and Kylie Jenner didn't already graduate from high school?

Despite world-wide fame and pretty grown-up lives that play out across millions of television sets each week, the youngest of the Kardashian-Jenner clan are just 19 and 17, respectively.

Crazy right? It's easy to forget they're both still teenagers when the twosome own their own homes, clothing lines, and are establishing pretty respectable careers for themselves.

Although Kendall technically graduated last year, it's not really graduation unless you have a party hosted by Ryan Seacrest (not kidding), complete with photo booth, stick props, and of course, lots of selfies.

What, you didn't have giant CONGRATULATIONS balloons and blow-up swans at your graduation party? Okay, we didn't either.

The surprise bash had plenty of famous guests (of course), including model Gigi Hadid and brother-in-law Kanye West, see all the snaps straight ahead and try not to get serious FOMO.

Werk it, Kylie. The girl can even make diplomas look good. She captioned this snap, "I love my mom for doing this. Thank you for making this experience as normal as possible for me. Yay? I graduated :)"
