Demi altered a part of the song lyrics from "why don't you stick to acting?" to "why don't you stick to tambourine?"

The teen singer didn't mention Joe's name on that line, but many believed that the line was referred to him as the middle of the Jonas Brothers occasionally plays tambourine in addition to taking the mic when performing with his band.
