Bella Thorne and Zendaya didn't really get along in the beginning of their show, Shake It Up. They eventually were able to move passed it and are still friends to this day.
"Zendaya and I were put in a very unfortunate position where we were kind of forced to compete against each other, which made the whole first season of the show just very awkward for us," Bella told J-14. "We wanted to love each other, but yet we were constantly being put against each other. It was, 'Who's better at this?' and 'Who's better at that?' And then second season we kind of just had this tell-all talk where we started crying and really just put everything out there on the table, and that's when we became best friends."
