We have reported last year about Seo In Young's special featuring for OneTwo's song, Bad Girl. Oddly, Seo In Young seems just too perfect for the role! After all, she is known for her wicked charm under the nickname of a "witch" she gained from the show, MBC We Got Married. But I guess a year is enough for someone to change their image. The picture above suggests nothing about her being "evil" at all. OneTwo recently finished their promotions for their song, "Starry Night". I guess they are quite a restless duo, for they proposed to unveil another song, "Bad Girl II" on the 23rd. As the number two after the title explains, the song will be the second version of "Bad Girl". The promotion for the song is still uncertain at the moment. OneTwo's record label, Happy Face Entertainment, stated, "OneTwo and Seo In Young are very good friends, which ultimately resulted in her featuring for the "Bad Girl II", as well as the preceding version." They also added, "Jewelry are quite busy because of their promotion for "Vari2ty", but she managed to adjust her schedule for this occasion. We thank her gratefully for helping us out to produce a such an amazing song." Here is the original Bad Girl. What a harmony of rap and vocal! Wonder how the second version will turn out...
