Kate Middleton Birthday: The Duchess Turns 30, Plus Other Royals At Age 30 (PHOTOS)

PHOTOS: Celebrating Royal Beauties At Age 30!

Major royal celebrations are in order, because (believe it or not) Kate Middleton is turning the big 3-0!

At 30 years young, the Duchess of Cambridge has a lot to be celebrating. This past year was a major one, what with becoming a British royal as well as a fashion obsession and one of the most buzzed-about people of the year.

So how will Catherine and her new high-profile family be marking her milestone today? Rumor had it that Kate's birthday bash was planned by Pippa Middleton and Prince Harry, who certainly know a thing or two about partying -- word on the street was that the extravagant party would be "'80s-themed."

Alas, actual reports say the party will in fact be a "low-key and private" event. So instead, we've decided to celebrate the duchess' big day in our own way: by taking a look back at other lovely royals back when they were in their young thirties.

Check out these lovely duchesses, princesses and queens the way they were. Happy birthday, Catherine!
