Kardashian matriarch Kris Jenner hosted a surprised graduation party for her daughters Kylie and Kendall Jenner, as well as Khloe Kardashian on the November 29 episode of Keeping Up With the Kardashians.

Ryan Seacrest, Alan Thicke, and Kendall Jenner’s best friend Gigi Hadid were also present at the star-studded celebration. Kylie, 18, just graduated from high school this year while Kendall, 20, graduated in 2014.

Their mom Kris was not aware her 18-year-old daughter would finish high school in a week since she was homeschooled. Upon learning Kylie is about to graduate, the generous mom enlisted the help of her older daughters to plan a surprise graduation bash. Besides Kylie and Kendall Jenner, Kris also honored Khloe, who never had a graduation because she was also homeschooled like her sisters.

The party, which was held at mom Kris’s house, looked like a real graduation ceremony with the girls wearing their caps and gowns. Seacrest served as the emcee and presented the diplomas to the “graduates.” Afterwards, Kris delivered a short yet sweet and touching commencement speech for her girls.

The graduation party was a huge success. There were synchronized swimmers in the pool, a sushi bar, and their famous Kardashian photo booth. Proving that they are not your typical high school graduates, Kylie and Kendall Jenner got diamond Cartier bracelets as their graduation gifts.

However, one person was not invited to Kylie and Kendall Jenner’s special graduation ceremony. Apparently, Kris was not ready to see her former husband after his transition to Caitlyn Jenner and she wanted to make the event very special for Kylie and Kendall Jenner.

“I’m just trying to process it, not alienate anybody,” Kris explained. “I don’t want to hurt Kendall and Kylie but at the same time I need time to adjust to this whole thing.”
