SISTAR appeared on MBC FM4U's 'Kim Shin Young's Noon Song of Hope' on July 3 where members Soyu and Hyorin's drinking habits were revealed!

Hyorin said, "Whenever Soyu gets drunk, she kisses.  I'm going to have to wear a mask when I drink with Soyu.  I don't like it when a girl kisses me, but Soyu kisses so much."

Kim Shin Young asked, "Why do you kiss so much?" and Soyu replied to everyone's amusement, "Maybe I was lonely, so I did that..."

As for Hyorin, it was revealed that her way of speaking changed.  Although she always speaks in a chic manner, once drink gets in her, she changes into an affectionate, friendly, and cute way of talking!  The members even mimicked her way of speaking after intoxication, making Hyorin embarrassed.

She said, "When I get drunk, even I think, 'I've gotten friendlier.'"  Soyu added, "Once in a while, she even speaks formally," and Dasom said, "I think that's the best drinking habit in the world."
