Kendall & Kylie Jenner Celebrate High School Graduations Together!

Kendall and Kylie Jenner take a family photo with their three older sisters while attending their graduation party on Thursday night (July 23).

The two reality stars were joined in the photo by Kim, Khloe, and Kourtney Kardashian. Even though Kendall graduated from high school a year ago, they celebrated the occasions together.

“I love my mom for doing this. Thank you for making this experience as normal as possible for me. Yay. I graduated :)” Kylie wrote on Instagram.

During the party, which was hosted by Keeping Up with the Kardashians executive producer Ryan Seacrest, the sisters were seen twerking and taking lots of snapshots in the photo booth. See all the pics in the gallery and watch some videos from Snapchat below.
