SISTAR's agency, Starship Entertainment, has just announced that they're preparing to debut a new male group for next month! The secret male group was once revealed on MBC's "Quiz That Changes the World". At the time, they had appeared as K-Will's back dancers, and wore masks that covered their faces. The members are rumored to be Jo Young Min, Jo Kwang Min, Yunho, TNT, and No Min Woo. Jo Young Min and Jo Kwang Min both made appearances in SISTAR's music videos, while Yunho rapped at K-Will's concert; meanwhile, TNT was chosen at an audition in Thailand, and No Min Woo had a cameo on MBC's daily sitcom, "All My Love". A representative stated, "We are currently preparing a male group and have finished recording their album's title track. They will debut by end April, but we have yet to decide on their name or the total number of members. We've noticed the rumors about how the group would have seven members, but we're considering 5 or 6. They will definitely be different from the other male groups in the market."
