The former power couple had been dating for almost nine years before calling it quits in November 2019.
According to an insider, Hudgens, 31, and Butler, 28, were in two different places when it came to their careers, and eventually, it took a toll on their relationship.
“Austin’s career has really skyrocketed in the last year,” the source explained. “He appeared in Once Upon A Time In Hollywood and he’s starring as Elvis [Presley], so for him he is just focusing on that and it really impacted his relationship with Vanessa.”
The stars — who began dating in September 2011 — sparked breakup rumors after seemingly failing to spend the holidays together.
