The lovely girls of TaeTiSeo seem to be having a lot of fun trying to show off their swag. The girls lip-synced to Iggy Azalea's "Fancy" and Big Sean's "I don't FuXX With You" on videos posted via Tiffany's Instagram account! Even the typically prim and proper lady Seohyun and is proudly "thugging out" and showcasing her "gangsta" side in these fun, just-for-laughs video.�

Decked out in all black and with hoodies donned over their heads, the ladies of TaeTiSeo show us that they can be not only cute and classy but also cute and bada$$ (it's not easy to be both).�
