Kourt, Khloe and I had so much fun looking through all of your entries in our 'Costuming Up with the Kardashians' competition! We didn't expect to get so many pics of adorable kids and pets too!!! It was really tough choosing our top three costumes, but we whittled it down in the end and all agreed on our favorite... Celebuzz posted a gallery of our favorite 40 in a costume countdown, so click through to find out who our grand prize winner was!

Thanks to everyone who entered!
