The ladies of AOA, one of the newest rookie girl groups in the business, reached a milestone today as they celebrated 100 days since their debut.

Posing with a small cake, the members gathered to mark this special occasion, having managed to survive the brutal K-Pop industry - so far.

Member Jimin added, "Hello!! This is AOA's Jimin!! It's already been 100 days thank you for all your love for the past 100 days!! Us angels will make sure that we work even harder from now on!! We love you ?"

Congratulations to AOA on reaching this special milestone!
