It's Sarah Michelle Gellar 's birthday! The actress, who has been making a name for herself in Hollywood for more than 15 years, turns 37 today.

They did give us a rare glimpse at their private lives in a sweet Twitter snap SMG shared  last month to celebrate reaching 200,000 followers — but that's not the only memorable photo of the duo. Keep scrolling to see our absolute favorite pictures of SMG and Freddie through the years.
