When it comes to celebrity crushes, Adam Brody has topped our list since he played lovable geek Seth Cohen on The O.C., but since the show ended in 2007, we haven’t seen nearly enough of him.

But when the gorgeous actor does grace us with his presence, we’re shocked. Sadly, it’s not because he’s gotten back together with Rachel Bilson, but because he hasn’t aged a bit in the past six years! If anything, he’s aged backwards, looking even younger and more dapper now than during his Orange County days.

Instead of just comparing the photos side by side, we propose a test. Can you tell which photo was taken in 2006 and which was taken this year? We’ll give you a moment to decide …

OK, brace yourself: The photo on the left was taken at the Thank You For Smoking premiere in March 2006 and the photo on the right was taken at the Damsels in Distress premiere in March 2012! Six years later, Adam looks incredible. The only thing that appears to have changed is his style — hello, suit! — and his choice of hair products.

And if you were wondering what Adam is up to now, he has five films coming out this year, including playing ‘70s porn star Harry Reems in Lovelace with Amanda Seyfried. We also have a theory that he’s the real Benjamin Button.

Did you guess correctly? Tell us below, and feel free to share your favorite O.C. moments in the comments! We’ll also take Dave Rygalski quotes if you have ‘em.
