SK TWorld (a telecom company) has been dropping hints on its official Facebook and Twitter accounts for the past few days about the guests that will attend its event, Christmas T Social Party, on the 24th at Club Heaven. Obvious clues like "hip-hop duo", "fashionistas", "VIP", etc. were posted so BIGBANG fans already knew more or less which members will be attending.
Yesterday, December 5, they uploaded a video ad on Youtube confirming the celebrities that will be present at the event. The list of the confirmed guests includes BIGBANG's G-Dragon and T.O.P, Se7en and Leessang. See video below:
