Kourtney Kardashian turned 41 on Saturday, and her close friends and family participated in a high-energy parade outside of her house to celebrate while still practicing social distancing to prevent the spread of COVID-19.

A stream of cars filled up the street as they parked outside of Kourtney's home. Guests blasted "Birthday Cake" by Rihanna, popped their heads out of the window to cheer, and held up balloons and signs before the reality star emerged with two of her children, whom she shares with ex Scott Disick.

Her sisters Kim Kardashian West, Khloe Kardashian, and Kendall Jenner were all parked close to Kourtney's house for the parade. And Kim's two oldest children, North and Saint West, were also present.

Khloe, who wore a bunny mask and sat on the roof of her car, brought her ex Tristan Thompson to the gathering and hyped up the rest of the group by speaking into a megaphone. The couple broke up in 2019 but continue to coparent their daughter, True Thompson.

The parade also included a piñata, which Kourtney's son Reign and Kim's son Saint took turns trying to crack open with a bat.

Aside from celebrating during the parade, members of the Kardashian family shared their own birthday messages to Kourtney on social media.

Khloe wished her sister a happy birthday on Instagram and shared a series of photos of them together, calling Kourtney "my best friend, one of the rare few I can count on most in my life."

"You and I have an incredible rare bond that no matter what, it can never be broken. (Yep! You're stuck with me!) You are my best friend, one of the rare few I can count on most in my life. I know that so many people go through life without their sister as their best friend. That thought alone breaks my heart. Thank God I was blessed with the most incredible siblings I could dream of. Honestly, without you my life would be boring, not as full and my life would always feel as if something was missing," she wrote.

Kim posted old family photos of her and Kourtney and wrote, "I had to find some good throwbacks to celebrate you today! I remember these moments so vividly. I love your strong will to do whatever makes your soul happy, the love you have for you children and for being the best big sister. I couldn't be more thankful for our memories together."

She continued, "You pack a mean punch I love you so much and can't wait until this is all over so we can celebrate together," referencing their on-screen fight on season 18 of E!'s "Keeping Up With the Kardashians."

And although Kourtney's mom Kris Jenner wasn't in the videos at the parade, she shared photos of Kourtney and her late father Robert Kardashian on Instagram along with a birthday message.

"I love your amazing zest for life and the way you love your kids and all of us around you... thank you for teaching us to slow down and smell the roses.. You are an amazing daughter, sister, friend, and mommy and I'm so blessed and grateful God chose me to be your Mom," she wrote.
