Happy Birthday to our favorite Olympic gymnast, Kayla "Mighty Mouse" Ross! You might be petite, but your legendary flips and fearless performance at the 2012 London Games soared higher than anyone else—even Mighty Mouse himself would do a double-take. Watching you help capture team gold was like witnessing superhero moves perfectly disguised in sparkling leotards.We wish you another year of perfect landings, unstoppable confidence, zero wobbles on life's beam—and as few height jokes as possible. Keep flexing those mighty muscles (and smiles)—because let's be honest: flipping upside down and still looking fabulous never goes out of style!
