Cassadee Pope’s performance pulled some serious heartstrings on The Voice last night— most notably those of her coach Blake Shelton.

The Voice hopeful sang "Over You," a song Blake co-wrote with his wife Miranda Lambert about the death of his brother.

Cutaways of the country crooner during the tune showed a tearful coach, but it was Blake’s off-stage reaction that showed the aspiring vocalist just how much the song meant to him.

“After the cameras were off, after the performance, he came up and gave me the biggest hug and said, 'Thank you so much, you have no idea how much that meant to me,'” Cassadee says of her proud coach Blake. “And that meant a lot to me. I know how special that song is to him and Miranda and I just wanted to do it justice. It meant a lot that he appreciated it.”

While the song is personal to Blake, Miranda chose to cut the song on her “Four The Record” album after her husband feared he would get too emotional to sing it live.

And Cassadee Pope felt the intensity in the room while she attempted to belt out the song that holds a special place in the heart of her 36-year-old mentor.

“It was very emotional, I felt very connected with it and I was so happy that Blake was proud,” the 23-year-old admits. “All I wanted was for him and Miranda to approve and I feel like he definitely did. Miranda hasn't watched it yet so… we will see what she says.”
