Brett Eldredge always puts on a good show, but Saturday (Sept. 15) at Y'allapallooza in Kansas City, Mo., he made one young fan's experience something she will remember all her life.

Apparently, Eldredge noticed a little girl in the audience who was behaving like a true fan of his music, and he decided to reward her by inviting her on stage to sing a duet of his 2014 hit "Mean to Me."

"She was crying and singing every word all night in the crowd...so I brought this sweet soul up on stage and she melted all of our hearts," noted Eldredge on his social media.

Indeed, the entire encounter was too cute for words."You ready to sing with me?" Eldredge addressed the little girl. "Just me and you. I'm gonna put the microphone down here. We're gonna sing the chorus, now."

She was indeed ready, and so was the entire audience—which sang along, as well. After a slightly hesitant start, Eldredge's duet partner found her voice and gave it her all, letting the entire venue hear her clear, high pitch.

After finishing, Eldredge gave his singing partner a hug and said, "You're the best, I love you so much!"

Eldredge is currently on the fall leg of his Long Way Tour, which runs through October, with Devin Dawson and Abby Anderson serving as opening acts.
