Kelsea Ballerini performed her new single "Peter Pan" at the Academy of Country Music Awards in Las Vegas on Sunday, April 3. And, as if performing wasn't a dream come true for the singer, she got to share the stage with her childhood crush, admitting she once thought she would marry him.

Her childhood crush was none other than Nick Jonas and can you really blame her? So many girls her age shared the same crush growing up.

Jonas, 23 announced on Twitter March 29 that he would be joining Ballerini on stage for 'something special.'

"I thought I was going to marry him when I was 13 years old," the singer told The Tennessean after taking home the award for Best Female artist. "So it's very casual that I'm on stage with him."

Sure, totally casual. Nothing to freak out about on national television.

Props to Ballerini though for nailing her performance and keeping her inner Jonas Brothers fan girl contained while standing so close to Nick while he played the guitar.

Prior to taking the stage with the hearthrob, she took to Instagram about the upcoming performance and even threw out a subtle pun to get Jonas' new single "Close."
