Big Bang's T.O.P. is notorious for being a sub-par dancer but it seems he's vastly improving in that department. On December 3rd, YG Entertainment held the '15th Anniversary YG Family Concert' at the Olympic Gymnastic Arena in Seoul. In the middle of the concert, Big Bang's T.O.P. was caught via fancam having an impromptu dance battle with PSY. T.O.P. showed off amazing footwork and fellow member Taeyang should watch out for T.O.P. and his smooth moves. YG Entertainment will hold a second concert on December 4th and then move the concert to Japan next month. Tip: Imane
