When Mandy Moore and Zach Braff started dating in 2004, they were considered something of an unlikely couple. She was a squeaky clean 20-year-old pop starlet and teen movie lead; he was nine years her senior and the star of Scrubs, as well as a respected actor-director on the indie film scene. Two decades later, and with Moore now highly-respected herself following her success on This Is Us, it somehow makes a little more sense.
