Nick Jonas performing at the American Country Music Awards? I know, it sounds surprising, but it's actually a dream come true for Kelsea Ballerini.

Kelsea told Entertainment Tonight "It's so killer to have one of my favorite artists . . . and someone who I may have had posters on my walls of when I was a preteen . . . be a part of my first-ever, full-out awards show performance." If that's not the most adorable reaction to a duet I don't know what is.

And, while Kelsea was having a fan-girl moment, Nick took to Twitter to talk about his excitement for their ACM duet.

Looks like Kelsea is calling "Dibs" on Nick, I hope no one get's "Jealous"... Ok, fine that was lame, but I had to do it!
