It looks like they weren't rumors. There will be a sub-unit of Girl's Generation, called Taetiseo. The group is composed of Tiffany, Seohyun, and Taeyeon. Their first mini Album will be called "Twinkle." The group's first music video will be out on May 2nd. Are you looking forward to this new group? If you could create a group, who would you want in it?
