This time the released clip is from his upcoming movie, Believe: 3D, and in it he talks about dealing with heartbreak and keeping a smile on his face.
"I could be going through a big argument, and I'm like, 'I'm about to go on stage right now.' And we were yelling...and like then I got to rise up on the toaster."
He adds, "[Sometimes] I'm upset, and I don't want to have to smile."
Of course, in typical movie trailer fashion, it keeps us hanging and wanting to know who he is talking about arguing with! Was he referring to his fights with his girlfriend-at-the-time Selena Gomez?
