Ahead of the release of their 5th Japanese single, Beautiful Hangover, the boys of Big Bang recently released a short music video teaser for the catchy song. In the teaser, we get to see each member with a special lady and get to hear a glimpse of their new song to be released on the 25th (even though they already performed it live). Check it out below, and stay tuned to Tokyohive for updates regarding Big Bang's return in Japan. http://www.youtube.com/watch?v=Zg1Yk_BrOCc [Many thanks to everyone who sent this in!]
