As if it wasn't bad enough that Zac Efron wasn't on hand with his High School Musical co-stars to promote the 10 year anniversary of the franchise for the Disney Channel special airing tonight, or hit the road with them visiting TV stations to promote the movie and its anniversary, now he has DISSED the popular franchise!

During an appearance on The Ellen Show this week, Zac opened up about his girlfriend Sami Miro, his new movie Dirty Grandpa and his co-star Robert De Niro. Zac revealed that while he knows all of Robert's previous work, the actor hasn't seen anything Zac has been in.

Zac scoffed at the idea that Robert could have possibly seen him in HSM, totally dismissing the franchise as a movie without merit. We're over here having none of it.


Watch Zac diss the one and only HSM below, and let us know your thoughts on his comments!
