Hyeri is Audrey Hepburn for 'Ring My Bell'

Girl's Day release the 3rd jacket photo for 'Ring My Bell' featuring Hyeri as Audrey Hepburn.

Hyeri is groomed with the star's remarkable hairstyle. Hyeri looks so suited in this transformation because she's slim and petite. Aside from the photos, Hyeri also takes note and apologizes about making fans worry over her injury. She makes sure there's nothing to worry about their upcoming comeback.

Now, we just have to wait for Yura's. Any guesses?
