Name a better duo than Clarisse Renaldi and Mia Thermopolis. I'll wait. Julie Andrews and Anne Hathaway brought this iconic Princess Diaries pair to life back in 2001, and despite the almost two decades that have passed, the bond between them is still strong. For Julie's 83rd birthday on Oct. 1, Anne shared a heartfelt note for her onscreen grandmother that'll leave you deep in your emotions.

"The knowledge that power is nothing without respect;Why one must have patience, positivity, perspective, manners, kindness, and humility. Always, To everyone,(No exceptions); The joy in treating people as a gift rather than a burden; How far choosing gratitude can get you. . ." Anne wrote in her Instagram photo's caption. "If I know anything about any of this, It's because I was lucky enough to have learned from the very best at the very beginning. Happy Birthday Julie, Queen Eternal."

Aw! The royal family of Genovia is still standing strong. Check out more of Anne and Julie's sweetest moments from their time filming together, ahead. If they ever wanted to get the original cast back together and film a third instalment, I sure wouldn't complain — seems like Mandy Moore's nostalgic for those days too!
