For some reason, their famous parents decided to throw the bash in advance of their birthdays. North will be 5 on June 15, while Penelope's sixth birthday won't happen until July 8. It might mean that they celebrations continue until their actual birthdays.

Wait until you see how things went down at this year's party!

We know the family dropped dollars on the decor. However, it like an easy and cheap project to replicate for a kid's birthday party. The stools could be made with waste baskets covered with a faux fur fabric.
