Entertainment TV Kardashian Family Surprises Kourtney with Socially Distanced Birthday Parade in KUWTK Sneak Peek The reality star turned 41 on April 18 By Aurelie Corinthios Published on September 4, 2020 12:36 PM Share Tweet Pin Email Earlier this year, the Kardashians got together — from a socially appropriate distance — to celebrate Kourtney Kardashian's birthday during the COVID-19 pandemic. In a sneak peek from the second half of Keeping Up with the Kardashians' season 18, Khloé Kardashian rallies family and friends to surprise Kourtney with a car parade for her 41st birthday. "We're going to drive by Kourt's house blasting birthday music, honking horns, annoying all the neighbors," she explains in the clip. "Everyone did such a great job decorating their cars." The Kardashians Are Getting New iPhones Every Week to Self-Film KUWTK During Coronavirus As guests begin to gather in the neighborhood from the safety of their respective vehicles, Khloé, 36, enlists Kourtney's 8-year-old daughter, Penelope, to get her mom outside. "Penelope, can your mom hear me? Okay, because we have a surprise, so I'm going to need you to do something for me," she says over the phone. "I need your help with getting your mommy out the front door and I'm going to have a surprise for her on the street. You're just going to have to say, 'Mom, can you come outside? I need to show you something.' But don't ruin the surprise! You can take all the credit." The plan goes off without a hitch, and Kourtney looks genuinely surprised by the lineup of familiar faces as everyone honks and cheers. Cameras even catch Kim Kardashian West's daughter North, 7, waving from the sun roof of a Range Rover.

"She was just grateful to wake up with her kids around. She is always the happiest with her kids," the source said. "She received multiple flower deliveries and felt very treated. Her family and friends also celebrated her with a drive-by parade." "About 20 cars lined the street outside Kourtney's house. Everyone that she loves showed up. The cars were decorated with balloons and happy birthday [signs]," a second source added. "It was a surprise for Kourtney and she loved it." But the best surprise of all came from Rob Kardashian, 33, who presented his sister with a particularly sentimental gift: their late father Rob Kardashian Sr.'s record collection.
