Happy 40th birthday to the one and only Anna Kendrick! On this special day, we celebrate your talent, humor, and overall awesomeness. Who would have thought that the girl from "Up in the Air" would grow up to become a household name and earn an Oscar nomination? You make 40 look like the new 30 with your youthful energy and charm. Keep slaying on and off the big screen. Here's to many more years of making us laugh, cry, and sing along to your fabulous performances. Cheers to you, Anna!
