On the January 4 airing of KBS2 'Happy Together 3', Ailee joined as the guest for the 'Sing My Song' segment.
During her appearance, Ailee revealed, "I'm always on a diet to maintain my weight. One time, my diet was so severe that I felt a sudden dizziness when hitting the high notes."
She added, "But my body is so strong. I almost collapsed but my thighs withstood it."
