Efron gave the hint of their breakup after he deleted all their photos from his Instagram account. The High School Musical actor has also stopped following her on the photo-sharing app. Sami on the other hand still has their photos on her Instagram.
This act proves that it was Zac who called it quits and not Sami. His packed schedule is said to be the reason behind the split as the actor hardly has any time for his personal life. The couple was spending a lot of time apart which created cracks in the relationship.
