From Blake Lively and Ryan Reynolds to Zendaya and Tom Holland, plenty of the most iconic Hollywood couples were costars first. A lot of actors who started in the business young also found their first love (or at least one of their earliest relationships) on set.
Here are 17 Disney and Nickelodeon costar pairs who dated:
Dove Cameron’s “first ever real relationship” was with her Liv and Maddie love interest, Ryan McCartan. They got engaged after three years together then broke up six months later.
Good Luck Charlie love interests Bridgit Mendler and Shane Harper met during the casting process. After being friends for several years, they got together towards the end of the show’s run and then dated for four years.
Though neither ever directly confirmed it, onscreen High School Musical: The Musical: The Series couple Olivia Rodrigo and Joshua Bassett reportedly dated offscreen during the show’s first season.
