T-Ara revealed a picture at the waiting room before going on the stage.

Today, T-Ara took a picture holding up posters with messages to their fans in the waiting room of Mnet "M! Countdown."

In the pictures, the posters read, "Good Bye Number Nine, we are leaving with much love. We'll be back on December 2 with a song that beats 'Roly Poly.' Please be excited" along with cute drawings on the sides.

T-Ara will be back with the song 'What Should I Do?' on December 2.
