Entertainment TV Kylie Jenner Reveals That She Has Officially Graduated From High School Kylie Jenner, 17, told her Twitter followers her exciting news on Tuesday By George Stark Published on July 21, 2015 07:00 PM Share Tweet Pin Email Photo: Courtesy Kylie Jenner Who knew Kylie Jenner was so studious! The 17-year-old Keeping Up With the Kardashians star revealed to her Twitter followers on Tuesday that she has now officially graduated from high school. Sharing her exciting news with fans, Kylie wrote: “I finished school last week” adding: “I know I never post on social media when I’m in class but that doesn’t mean I don’t encourage education!” It’s been a busy time for Kylie recently, who last week attended the ESPYs to support Caitlyn Jenner getting the Arthur Ashe Courage Award for bravery. She also joked last week that she had grown up too fast after posting a flashback picture from her reality show. But for now it seems Kylie will be busy celebrating school being out for summer – and forever.
