Anne Hathaway is bowing down to the queen.

The star, 35, paid tribute to Julie Andrews on Monday, when the legendary actress turned 83.

Hathaway marked the occasion by posting a photo of her co-star from the 2001 movie “The Princess Diaries” on Instagram, where she spoke about the importance of several virtues.

“The importance of grace; 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…” she wrote. Hathaway added, “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.”

In “The Princess Diaries,” Hathaway played a San Francisco teenager who undergoes “princess lessons” after she finds out she’s actually the princess of Genovia, a fictional Monaco-esque country. Andrews played her grandmother, Queen Clarisse.

The two stars later teamed up for a 2004 sequel, “The Princess Diaries 2: Royal Engagement.”
