Mandy Moore has proved herself the throwback queen of Instagram before, often looking back at some of the films that defined the aughts 鈥 not just for her, but for us, too. Her latest is a tribute to the 2001 film The Princess Diaries, and it has us feeling all kinds of nostalgic.

The This Is Us star posted a photo with some of her castmates and reminisced about their time on set together. 鈥16 year old me with the inimitable @julieandrews and @heathermatarazzo on the set of #theprincessdiaries,鈥 she wrote, before pointing out some of her long-abandoned teenage aesthetic choices. 鈥#thosecurlstho.鈥

In ThePrincess Diaries, Moore portrayed the popular girl in school, Lana Thomas. She bullied Anne Hathaway鈥檚 character, Mia, which resulted in the memorable 鈥Lana got cone鈥檇!鈥 scene when Mia smeared a chocolate ice cream cone all over Lana鈥檚 cheerleading outfit. Classic.

Matarazzo played Mia鈥檚 friend Lilly Moscovitz in the flick 鈥 but it鈥檚 not the only time the two starred opposite each other. The recently engaged Matarazzo and Moore were also in the 2004 teen comedy and religious satire Saved!, and the photos are just as era-appropriate.

鈥淚n honor of @mandymooremm鈥檚 #tbt photo, here鈥檚 a #tbt from when we shot #Saved and I was a blonde,鈥 Matarazzo captioned two photos of the costars seemingly singing karaoke together. 鈥淵ou were meant to play Hillary Faye and I am so happy you did.鈥 Us too!

Which movie do you like better: The Princess Diaries or Saved? Let us know @BritandCo!
