Earlier today, Big Bang's G-Dragon tweeted "In last year 'Gangnam Style'".

Along with the tweet he attached picture of himself, his fellow band member, T.O.P, and worldwide sensation Psy, holding up piece signs with silly party hats on their head.

G-Dragon, T.O.P and Psy are all currently artists on YG Entertainment and will most likely all attend YG's annual "YG Family Concert".
