Talented girl group 4minute recently unleashed a double-hitter in the form of a new EP and their first official album. Since two new releases mean two new title tracks, the girls have been practicing relentlessly to perfect the choreography for "Heart to Heart" and "Mirror Mirror". The result isn't all that pretty, and in fact, it can be a little alarming for their fans. A photo of the girls from their rehearsal room reveals the exhausted state that their whirlwind preparations have brought them to. Still, the girls aren't going to let a little fatigue stop them from killing their official comeback. They'll kick off their round of promotions through tonight's episode of Mnet's "M! Countdown", where they will perform both title tracks. We're sure that these girls are going to put on one heck of a show, so be sure to check back with allkpop for coverage on their comeback stage.
