Thrill-seeker Kendall Jenner gets her adrenaline pumping on giant inflatable slide as she and Kylie celebrate high school graduations with huge bash

They are two of the most famous teenagers in the world and Kendall and Kylie Jenner recently celebrated their graduations with a huge party. 

Supermodel Kendall, 19, completed her high school education while her 17-year-old sibling Kylie finished this year and to celebrate their mother Kris Jenner threw them a huge bash at her home in Calabasas, which was filmed for their reality TV show 'Keeping Up With The Kardashians'. 

While Kylie thanked her mother for making the experience 'as normal as possible', there was nothing ordinary about the party which featured a host of famous friends, reality TV cameras, Ryan Seacrest officiating and a huge blow up slide.

Steal Kendall's summer style in a striped tank by Brandy Melville

You know you're a supermodel when you can make a pair of jeans and a vest top look like this.

Kendall Jenner always looks incredible but even in this totally casual, pared down outfit, she's just leagues ahead. Those high-rise jeans by 7 For All Mankind fit her like a glove and with this cropped tank top, her waist looks tiny.

The tank is by stateside high street label Brandy Melville. It's a brand we've spotted on Kendall's younger sister Kylie before as well as her BFF Taylor Swift. And the great news is it's cheap as chips so is perfect for picking up everyday essentials that can work with the rest of your wardrobe. Unfortunately, the red-and-white striped colorway is sold out, but you can buy it in black. So click (right) to bag this simple summer top now and then style it with Kendall's skinnies from Farfetch (below). Add a pair of box fresh white sneaks and some cool girl shades and your off-duty model look is complete.

Their older sister Khloe Kardashian also tried out the combination bouncing castle and slide, in a leopard print dress. 

The party on Thursday, which marked Kylie's graduation earlier this month and Kendall's last year, was filmed for an upcoming episode of Keeping Up With The Kardashians.

Kourtney was also in attendance, as was pregnant Kim, along with husband Kanye West and two-year-old daughter North.

Also joining the festivities were Kylie's boyfriend Tyga and BFF Pia Mia, Khloe's best friend Malika Haqq and rumoured beau James Harden, and Gigi Hadid and pop singer Cassie.

'Thank you for making this experience as normal as possible for me,' Kylie captioned a dedication to momager Kris, who hosted the bash at her home in Calabasas.

In another post, the youngest daughter of Caitlyn Jenner - who was not at the event - showed off her diploma which read: 'Laurel Springs High School certifies that Kylie Kristen Jenner has successfully completed the Course of Study presented for graduation.'

She donned a black cap and gown in front of a poolside backdrop of silver balloons that spelled 'Congratulations.' 

The Keeping Up With The Kardashians starlet has been home schooled since leaving Sierra Canyon School in 2012.

'I love my mom for doing this. Thank you for making this experience as normal as possible for me. Yay I graduated!'  

In a couple of Snapchat videos, Khloe can be seen twerking to the music in a cheetah-print dress that featured a thigh-high slit.

On Saturday, the 31-year-old denied allegations that guests at the bash were taking drugs, after a video emerged of a man appearing to rub a substance in his mouth.

She tweeted: 'You guys will make up anything. No! No one was doing coke at a graduation party in broad day light with teenagers and 15 production cameras.

'We aren't as wild as you want to believe. We were taking Jell-O shots though and you have to scrap [sic] the rim of the shot glass w ur finger to loosen up the jello in order 2 take it. Just say no to drugs kids! Drugs so not our style.'

Kendall was dressed casually in a red and white striped crop top and high-waisted skinny jeans.

On July 21, Kylie announced on Twitter that she completed her secondary education: 'I finished school last week.. & I know I never post on social media when I'm in class but that doesn't mean... I don't encourage education! Because I do! gooooodnight.' 

As she completes one milestone, the teen is getting ready for another life moment.

Kylie will celebrate her 18th birthday on August 10 - when she's planning to officially leave home.

The Keeping Up With The Kardashians star bought her very own place in Calabasas, Calif., in February for $2.7 million, and has been decorating and moving in her stuff. She told Teen Vogue in May, 'I'm moving out when I turn 18.

'I'm ready to live on my own. It's a really big step, but I'm ready... I wanted a house near my family in a quiet neighborhood with a front yard and a backyard that my dog will like. Also, I have so many shoes, and none of them fit in my old closet.'
