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.

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.
