Aoora and Kimchi of new boy group AA received some flak yesterday for their behavior on KBS Music Bank. The boys could be seen trolling --that is, making various gestures and faces-- in the background while SNSD was being announced as the winner and also while MC Hyun Woo was giving his farewell speech on the show. Earlier today, Aoora came out and formally apologized for their behavior on twitter. Aoora tweeted in English,

AA apologize for what we did in KBS music bank yesterday. We were immature and senseless being such a big stage with all senior artists... we've respected for all times... Especially, we AA bow our head in apology to ?? ??? (Hyun Woo sunbae) who have been greatest MC in Music Bank for a long time... AA regret and reflect for what we did and promise that we will show you decent behavior... AA will do our best not to disappoint somebody who have cared for us."
