On an appearance on The Ellen Show, the host inquired about the song’s subject. “There’s supposedly a song about Nick Jonas,” Ellen stated to Demi, to which the singer said, “Ya know, something that I will always keep to myself is who I write my songs about.”

Camp Rock one and two were both huge successes for Disney Channel and made household names out of Nick, Joe and Kevin Jonas as the Jonas Brothers and of Demi Lovato. They all toured together as a group and then Demi Lovato revealed that after Camp Rock 2, her and Joe Jonas dated each other briefly but realised they were better as friends.

The band — consisting of brothers Joe, Nick and Kevin Jonas — kicked off their 20th anniversary tour on Sunday at MetLife Stadium in their home state of New Jersey. But to make it more special, they surprised their fans with some special guests throughout the show, including Demi Lovato .
