“I’ve learned more from her than anyone that I’ve ever gotten the honor to be in the room with, not just vocally,” Cyrus said. “I should have gotten more lessons than I did, but she taught me everything that I know about love.”

The “Malibu” songstress had her father, Billy Ray Cyrus, on hand to sing “Amazing Grace” as the singer was too emotional to get through the song herself.
