Happy 40th birthday to the fierce and talented Scarlett Johansson! It's hard to believe that our favorite Black Widow is officially over the hill, but we all know age is just a number. You've been slaying since your teenage years and have only gotten better with time. Here's to the next 40 years of dazzling us on the big screen and inspiring us with your badassery. Cheers to you, birthday girl! Leave the cake, take the diamonds.
