If you celebrated your birthday in isolation, the party would have been little more than a cake stocked at the local grocery store, a bottle of wine, and, if you were lucky, a zooming "Happy Birthday" serenade. Not so for Kourtney Kardashian, who turned 41 on Saturday: her friends and family, including Khloe Kardashian and Kendall Jenner, were treated to balloons, air horns, handmade signs, a tremendous amount of cheers, and loudspeakers playing Rihanna's "birthday cake" while They organized a parade of cars in front of her house. Khloe and Kendall documented the whole thing on their Instagram stories. But Khloe's lengthy birthday post (open in new tab) dedicated to her oldest sister makes it clear that all is well between them now.

"You and I are bound together by an incredible and rare bond that will never be broken no matter what. (Yes! You can never leave me!)" Chloe writes. 'You are my best friend and one of the few people in my life I can count on.'

"Today and every day, I pray that your soul is covered with love and that from your core, you are happy!" She continued. 'You deserve only that which is magical! I will love you in your former life and in your later life! To the happiest of birthdays: ...... My sister!"
