Girl group KARA revealed a group picture taken in the waiting room of 'M! Countdown.'

Today, Mnet "M! Countdown" posted on its Twitter, "Hello! Tonight at 6PM, M COUNTDOWN COMEBACK KARA" along with two pictures.

In the pictures, KARA members are gathered together in front of the camera, holding up paper mustaches and making funny faces. 

Internet users who saw this commented, "Thank you for showing us your bright smiles," "See you soon," and "So cute."

KARA came back today with their title song "Damaged Lady" of their 4th album "Full Bloom."
