Nicky Hilton is certainly no stranger to an over-the-top birthday party. Especially when it comes to her two daughters.

Decking out her mother Kathy's luxe LA mansion (as now appears to be tradition) with all things pink, a bouncy castle, bubble blowing fairy(?), guest appearance by Elsa, and Peppa herself, Nicky documented it all in true Instagram fashion. Oh, and of course, in mommy-and-me matching dresses.
