Kourtney Kardashian Gets Surprised With a Socially Distanced Birthday Parade — See the Snaps!

Happy birthday, Kourtney Kardashian! On April 18, the lifestyle mogul turned 41 and enjoyed a self-isolation celebration with friends and family. She kicked off the special day with sons Mason, 10, and Reign, 5, as well as daughter Penelope, 7, who decorated the house with flower petals as a surprise for her mom. "I have the sweetest daughter in the whole world," Kourtney captioned an Instagram video showcasing the sweet gesture. Later in the day, the mother of three got another heartwarming gift from loved ones: a socially distanced birthday parade!

Some of Kourtney's closest loved ones — including sisters Kim Kardashian, Khloé Kardashian, and Kendall Jenner — showed up to her house in droves to wish her a happy birthday from their cars. Guests brought balloons and air horns as they lined up along the street while wearing masks and blasting songs such as Rihanna's "Birthday Cake," Trap Beckham's "Birthday Chick," and 50 Cent's "In Da Club." Kourtney documented the occasion on Instagram, writing, "Heard a bunch of honking and screaming and came out to this, best birthday surprise."

Khloé, who recently hosted a self-isolation birthday party for her daughter, True, got really into the spirit as she donned a bunny mask and gave Kourtney a shout-out through a megaphone. "The neighbors hate us lol," Kim joked in one of her Instagram posts. The Kardashian-Jenner clan also shared a few heartwarming social media tributes to Kourtney throughout the day. "I'm so blessed and grateful God chose me to be your Mom," mom Kris Jenner wrote. "I love you so much my gorgeous girl." Look ahead to see all the photos from Kourtney's socially distanced gathering!
