Kendall and Kylie Jenner celebrate graduation with surprise party

Kim Kardashian's half-sisters Kendall and Kylie Jenner celebrated their graduation on Thursday (23Jul15) with a lavish party.

Kylie finished her home schooling last week (ends19Jul15) and her mother Kris Jenner organised a surprise bash at their California mansion for the 17 year old and her sister Kendall, who completed her studies the previous year (14).

Kylie wore a black cap and gown and was presented with a graduation certificate at the event, which she documented on Instagram.com, writing, "I love my mom for doing this. Thank you for making this experience as normal as possible for me. Yay I graduated."

She was joined by Kardashian and her sisters Khloe and Kourtney, model Gigi Hadid, rumoured boyfriend Tyga and TV presenter Ryan Seacrest, who hosted the event.

Kardashian also detailed the night by sharing photo booth pictures on Instagram.com, showing the siblings posing with fake lips, moustaches and novelty glasses alongside the message, "Congratulations Kendall & Kylie Class of 2014 & 2015."
