Happy birthday to the one and only Hilary Duff! Can you believe that our favorite teen queen from Lizzie McGuire is now 38 years old? Time flies when you're busy slaying in the entertainment industry! From Disney star to singer to mommy to author, you've done it all and continue to do so with grace and style. Wishing you a day filled with love, laughter, and lots of cake (because let's be real, calories don't count on birthdays). Cheers to another year of fabulousness!
