The beastly boys of 2PM temporarily put away their dark looks and took on a playful mood for Calvin Klein, and just in time for the summer, too! On the 14th, a rep from Calvin Klein Korea said, "For this photoshoot, 2PM briefly got rid of their beastly charisma and made a transformation into more lovable pretty boys. 2PM exudes a youthful look as they wear t-shirts and jeans to go on a picnic and have a water fight." Even though we've got a month 'till the summer fun begins, no one can complain about seeing our boys topless and showing off their muscular toned bodies. As a wise man once said, "It's getting hot in here, so take off all your clothes." Check out the photos below! [gallery]
