Happy birthday to the talented, breathtakingly beautiful and ageless Billie Piper, who is now officially 42 years young as of September 22nd! It seems like just yesterday you were charming us all as the feisty Rose Tyler on Doctor Who, and now look at you, still slaying in all of your roles and looking phenomenal while doing it. Here's to another year of amazing performances, infectious laughter, and never-ending youth. Cheers to you, Billie!
