Khloe Kardashian had an extravagant birthday party that included an inflatable slide, pink balloons, and pillows of her face

• Khloe Kardashian celebrated her 36th birthday with a pink-themed party at her sister Kylie Jenner's house on Saturday.
• The event included an inflatable slide, balloons, and a plethora of sweets.
• Her family and friends came together for the party and shared an inside look via social media.

Kylie Jenner threw her older sister Khloe Kardashian a lavish party for her 36th birthday on Saturday.

The makeup mogul hosted the pink-themed bash at her newly purchased mansion in Los Angeles and invited Khloe's closest friends and family, who provided glimpses of the extravagant gathering on social media.

And though the Good American founder clarified the party was only for family since they "aren't comfortable being around too many people," she said that she had the "most magnificent birthday" and added that the decor was "out of this world."

From the moment that guests walked into Kylie's home, they were surrounded by pink decorations.

The entrance was lined with balloons and flowers, even displaying massive balloons that spelled out Khloe's nickname "Koko." The decor also featured pillows with images of Khloe's face on them.

Khloe's party also offered a plethora of pink-colored desserts, including a birthday cake with candles that she and her daughter True Thompson blew out together.

Similar to the giant inflatable head at Stormi Webster's 2nd birthday party, which was also organized by Kylie, Khloe had an inflatable slide with her face on it for the children to enjoy.

Khloe's brother Rob Kardashian made a rare appearance in photos and joined siblings Kourtney Kardashian, Kendall Jenner, and Kylie at the event.

Rob also shared photos with Kourtney, Khloe's ex Tristan Thompson, and Kourtney's ex Scott Disick on his own Instagram page.

The siblings showed their goofy side at the party and engaged in a playful fight, which was filmed by Kylie.

And while most of her children opted for edgy, casual clothes, Kris Jenner got dressed up for the party, wearing an emerald gown with fringes lining the sleeves.

She also carried a bedazzled purse that was shaped like a martini glass to carry alongside her real drink.

Khloe promised to post more of her own pictures from the party on Monday, telling fans that she was busy "balancing mommy life and recovering" over the weekend. However, she did show off her new brunette hair in a series of photos she took while posing with pink balloons.

"Tomorrow I'm flooding my time-line with party pics. Btw... I'm loving my brown hair. I never thought I would say that lol blonde still owns my heart but this brown is giving me a little something right now," she wrote.
