It's Sarah Michelle Gellar  and Freddie Prinze Jr .'s anniversary! Believe it or not, the couple has been married for 12 years.

Their adorable relationship only upped the fan frenzy. In the years since they became a Hollywood power couple, the stars have had two children together, but they've mostly kept their relationship under the radar. They did give us a rare glimpse at their private lives in a sweet Twitter snap SMG shared  in March — but that's not the only memorable photo of the duo.
