G-Friend get hyper covering and jamming out to Girls' Generation, EXO, Big Bang, and 2NE1

On the August 5 edition of 'Today's Room,' G-Friend shed their pure, innocent, and sweet image to go completely crazy karaoke-ing to Girls' Generation's "Gee," EXO's "Growl," Big Bang's "Bang Bang Bang," and 2NE1's "I Am the Best"!  They also did a freestyle version of their current hit, "Me Gustas Tu," showing a never-before-seen image from this rookie group.

SinB might be all smiles on stage, but she proved to have a very tough exterior as she keeps glaring at the camera with cool swag, almost appearing tomboyish in her mannerisms.  They sing and dance to "Gee" and "Growl" and even pretend to be shot with hearts by Umji wielding a huge gun for the "Bang Bang Bang" portion of their show.
