Now, I've never experienced the unlimited joys that comes with having a twin sister. I mean, imagine how cool it must be to have a built in best friend (forever) that literally completes your thoughts and understands all your feelings? No offense to my big sis (love you, girl!), but being a twin sounds pretty darn cool. Even cooler? Being a set of twins that are so in sync, like Nikki Bella and Brie Bella, that you literally get pregnant at the same damn time.
