Despite being one of the stars to stay most relevant with his fans, Zac has upset a large chunk of them recently.

Every 20-something year old holds HSM – High School Musical -close to their hearts. It's only natural that they would expect the actors of the movie to do the same. But maybe playing Troy isn't exactly Zac's most notable role in his mind. Or even the most memorable.

The star recently played a game with co star Emily Ratajkowski and director Max Joseph, where he had to guess the name of popular songs. When HSM's "Breaking Free" came on, he fell short – mislabeling it with an incorrect name. To be fair, Zac later did correct himself as they got further into the song. What's even more interesting is the fact that Efron claimed that it was his voice on the track, which had been debunked years before the interview.

HSM enthusiasts weren't thrilled.

Who has time for remembering songs when you're out searching for your fav sushi spot though? It's okay, Zac. We forgive you.
