A momentous date such as this only comes along once in a lifetime (for those of you who skew more Steve Sanders than Andrea Zuckerman, it's 9/02/10. Rad, right?!).

And what better way to mark the occasion than to collapse a love triangle by choosing you wax nostalgic on the OG TV hit by reliving one of its finest, would-be-forgotten guest starring moments, courtesy of E!'s own fearless leader, Ryan Seacrest.

"In honor of #90210day, I present u with my cameo on '90210' from a decade ago!" he tweeted. You see? Hosting was in his blood. (Just do yourself a favor and try not to stare directly at the frosted tips.)
