Rejoice, Castle fans! It's flashback Friday, Stana Katic edition.

Today, Castle's brunette beauty tweeted a picture of herself from her high school graduation party, which would have made her either sweet 17 or 18 at the time. Not surprisingly, she doesn't look much different than she does today at 34. Stana, please tell us your secret!

"World's a big place. Enjoy it, everyone! (Cutting the cake @ my high school grad) Big hug, Stana," she wrote on her Twitter page. Beautiful advice from a beautiful lady!

What do you think of Stana's flashback picture? Has she changed a lot since high school?
