Last week, we reported that Wonder Girls' leader Sunye released several BTS selcas of the group during the filming of their 2 Different Tears music video. However, more recently, the Wonder Girls uploaded an official BTS video onto their official Youtube channel! Although the pictures from last week were quite a sweet surprise for fans, I'm sure this video will delight the fans even more! This clip shows all the hard work the girls went through to put out an excellent music video. In addition, it shows some footage with the famed comedian Bobby Lee. Check out the video below! http://www.youtube.com/watch?v=JV6g4UbII74&playnext_from=TL&videos=nQWTtCFn5GI
