New boy band LC9's member Eden released a shirtless photo of himself and was quickly crowned the new 'collarbone idol' in K-pop.

LC9's debut song, "MaMa Beat," which was released on May 9, showed a part of his bare shoulder. In addition, another photo of Eden uploaded on Twitter exposed his sharply-defined collarbones and shoulders.

An associate from LC9 stated, "'MaMa Beat' received an R-rating for containing a number of borderline footages. Some risqué images of Eden from the music video caught attention from the public and have become a hot issue." On many online communities, Eden has been crowned the new up-and-coming 'collarbone idol' whose predecessors have been JYJ Yoochun, Jaejoong, BEAST's Yong Joonhyung, SHINee's Onew.

LC9 was labeled 'Brown Eyed Boys' for the sexual contents in their music video. With catchy lines and well-polished choreography, LC9 is making a name for themselves.
