After School's leader Kahi is often known for her strong and sexy stage charisma, but her latest update reveals a transformation that would have many doing a double take.

On May 12th, Kahi updated her Twitter with a new photo (above) showing off a new hairstyle, revealing that the singer has gone back to black with full, straight bangs across her forehead. This hairstyle tends to create a youthful, innocent look, and Kahi was no exception.

She tweeted, "Mighty Mouth's 'Bad Guy' Let it blow up~~~!!!!! Sangchu are you happy~~~??!! ke Fighting~~!!^^ Sangchu are you happy? Picture is hair change~^^"

Mighty Mouth responded, "MM at the same time, you're promoting and you're a beauty queen like a PR diva! ke Thank you!"

What do you think of this new style?
