When your mom is Kourtney Kardashian, you've got some cool birthday parties coming your way.

The 37-year-old reality star proved exactly how awesome of a mom she really is when she threw her sons a turbo-charged party themed after The Fast and the Furious over the weekend.

Mason and Reign, who turned 7 and 2 respectively on Dec. 14, were treated to a tricycle race track outside their home, as well as a massive bouncy house shaped like a giant car.

Kourtney even got her kids two separate racecar birthday cakes.

Kourtney rocked a black leather jacket and a patriotic bandana around her head as she posed with her pals under a silver balloon arch spelling out the name of the high-octane film franchise the party was modeled around.

Several of Kourtney's friends were in attendance at the party, as was her sister, Kim Kardashian, who brought along her own kids -- 3-year-old North and 1-year-old Saint, People reports.
