Around the 02:41 mark on the video, HyunA surprised her backdancer and concertgoers when she suddenly lifted up her skirt to reveal her booty on stage during a performance of Bubble Pop.
Though it seems the singer wanted to have some fun, there’s been a bit of controversy about her unexpected exposure.
On the 20th, HyunA addressed the controversy on Instagram, explaining her actions weren’t inappropriate for the party environment. She wrote, “The festival I went to yesterday was at a university, and right by was a simple bar with alcoholic drinks. It was a party where everyone could have fun partying. Please ease your heart, and don’t worry.”
The Instagram post has since been deleted.
