American Idol contestant Hannah Harper struck a chord with judge Carrie Underwood during her audition.

Harper sang an original song titled “String Cheese” about her struggle with postpartum depression on the Monday, February 2, episode of the long-running competition singing show.

Before performing the song, Harper recalled the moment that inspired her to put pen to paper.

“I was sitting on my couch wallowing, and you have boys, you know, everybody wants to touch you, and I didn’t want to be touched,” Harper told the judges Luke Bryan, Lionel Richie and Underwood, 42. “I was just having a pity party, praying that the Lord would calm my spirit, and my son kept coming up to me, ‘Mom, open this. Mom, open this, open my cheese.’ I’m like, ‘Leave me alone with the dadgum cheese.’ ”

“I finally opened his cheese, and when I did, I realized that God had put me in that place and that where I was in my house was the biggest ministry that I could ever have in being a mom,” Harper continued. “So, I gathered myself, and I got up off the couch, and I quit throwing a pity party, and I realized that was exactly what I wanted.”

After Harper performed the song, the “Before He Cheats” hitmaker — who shares sons Isaiah, 10, and Jacob, 7, with husband Mike Fisher — was in tears.

“Well, that’s about the most relatable song I think I’ve ever heard,” Underwood praised. “You might be my favorite person that’s walked through those doors in the past three days. You’re gorgeous, you look famous already. I just think you have just a beautiful simplicity to your voice.”

“You’re one that I’m going to think about when we leave here. Like I wonder what song she’s gonna sing next, and I feel like I’m gonna be just rooting for you,” Underwood added. “I loved everything about everything you just did.”

After receiving yes votes from all three judges, Harper advanced to the second round of the competition.
