Zac Efron Just Broke 'High School Musical' Fans' Hearts Everywhere

This is embarrassing.

Zac Efron's musical memory was put to the test while doing press for his new movie "We Are Your Friends." Efron, his co-star Emily Ratajkowski and director Max Joseph were asked to name songs after an interviewer from Cosmopolitan played the first few seconds of each.

Some were easy -- Ratajkowski knows her Beyoncé -- but when it came to a "High School Musical" song, Efron completely failed. Even listening to the lyrics to a song he had to lip sync (for what was probably multiple takes) didn't help him identify "Breaking Free" from the first Disney Channel movie. And the hearts of "High School Musical" fans shattered everywhere.
