Ashley and Lucas played the brother-sister duo Sharpay and Ryan Evans in High School Musical. While the characters didn't always see eye-to-eye, they still had each other's back. Nearly ten years after the film, the pair revealed that at the time, they despised each other.

In a YouTube video for Ashley's channel, she admitted that they "were not good friends." She then went back and added, "it's been ten years, we can totally talk about this...we hated each other." At least they're on good terms now.
