Kourtney Kardashian may have just closed out 2016 with one of the year's most epic birthday parties.
The 37-year-old proved she's one of the coolest moms around when she threw her sons, 7-year-old Mason and 2-year-old Reign, who share Dec. 14 as their birthday, an incredible The Fast and the Furious–themed party this weekend.
Not only did guests of the tots get a giant race track outside their home for tricycles and scooters, they also were treated to two over-the-top race car-themed birthday cakes, lights wrapped around the trees, cool Fast and the Furious gear, and a bouncy house that was inspired by a giant car.
The reality star, who was dressed in an American flag bandana and denim jacket in keeping with the theme, took to Instagram and Snapchat to share a series of images from the birthday bash. According to People, the festivities drew sister Kim Kardashian West and her two kids, North and Saint West, though husband Kanye West did not attend.
"Kim spent several hours at the birthday party with her kids. She looked very pretty and also seemed happy," a source tells the magazine.
