B1A4, who always brings smiles with their fun personalities and music, has done it again with a behind-the-scenes clip for 'Cosmopolitan'!

In addition to their recent pictorial, B1A4 took fans backstage of the photoshoot where the boys showed a little bromance and were all smiles for the camera. 

The group also couldn't hold in their excitement as they asked their fans to come see them at their upcoming '2013 B1A4 Limited Show - Amazing Store', this coming August.
