Happy Birthday, Sierra McCormick! From your hilarious antics as Olive Doyle in "A.N.T. Farm," you've given us countless laughs and unforgettable moments—like when you effortlessly rattled off random facts or navigated teen genius drama with comedic brilliance. Your quirky charm made every episode a joy to watch.

Beyond the halls of Webster High, you've continued to impress audiences with your versatility and talent in recent projects like "American Horror Stories" and films such as "The Vast of Night." Here's hoping this birthday brings you more cake than Olive had trivia facts—and that's saying something! Keep shining bright!
