Kourtney Kardashian Throws 'Fast & Furious' Themed Party for Mason & Reign!

Kourtney Kardashian threw a Fast & Furious themed birthday party for her two sons Mason, 7, and Reign, 2, who were both born on the same day!

The boys celebrated their big day this weekend – their actual birthday falls on December 14.

The party was apparently “low-key” and Kourtney posted some videos and photos after the bash.

The full guest list is not yet known, but hairstylist Jen Atkin was in attendance, and made an appearance on Kourtney‘s social media at the party.
