How Old Was Anne Hathaway In The First Princess Diaries

Okay, let’s settle a debate that’s been brewing since Y2K fashion made a comeback (and no, I’m not talking about low-rise jeans). You’ve watched The Princess Diaries roughly 47 times, you can quote every Mia Thermopolis stammer, and you still wonder: how old was Anne Hathaway when she first stepped into those gloriously unpolished loafers?

The answer is seventeen. Yes, our beloved Mia was sixteen in the film, but Anne herself was a baby-faced seventeen-year-old when she auditioned. By the time cameras rolled in 2000, she’d just turned eighteen. So she was playing a high school junior while being a high school senior in real life. Basically, she was living the plot—minus the royal grandmother and a makeover from a salon that definitely doesn’t exist in real life.

Think about that. At seventeen, most of us were worrying about prom dates or memorizing lyrics to Bye Bye Bye. Anne was acting alongside the legendary Julie Andrews, learning to fake-drive a 1960s Mustang, and making us all believe that braces and a bushy brow could be transcendentally charming. The guts it takes to rock that awkward phase on film? She made it look effortless, and honestly, it’s a masterclass in owning your weirdness.

So the next time you feel like you’re stumbling through your own “Transformation Scene,” remember: Anne Hathaway was just a teenager when she taught us that princesses don’t have to be perfect. They just have to be brave enough to try. And that, my friend, is a glow-up that never ages.
