We're still in mourning over last year's biggest breakups like Johnny Depp and Vanessa Paradis's split and today's news of Josh Brolin and Diane Lane's impending divorce. While cute pairs like Ryan Gosling and Rachel McAdams may not have made it, they have found new happy endings. So take a walk down memory lane as we look back to the red-carpet romances that were.
