It's hard to believe that it's already been three years since the girls took the K-pop scene by storm with their debut song, "Bad Girl Good Girl", which quickly ranked #1 and launched miss A into power rookies.

Suzy shared on her Twitter, "Thank you so much to everyone who congratulated us on our 3rd anniversary. I received the letters and presents well! I don't know if I even deserve these things. Thanks to you, the past three years have been filled with happiness. I won't forget that heart and continue to work hard!"

She also gave a shout out to international fans, sharing, "Thank you for all of your love and thoughtful presents.. S2."

Min also tweeted, "A shaky photo taken three years ago. Thankssssss I made the right decision in coming to my agency."

Jia shared a photo of the cake their fan cub, Say A, sent with the hashtag "#3yearswithmissa". 

Congrats, miss A!
