On the latest episode of KBS's "Hello", the girls of Rainbow made a shocking confession regarding their onstage hygiene. "It's embarrassing if you have to perform when you have to go to the restroom", Jaekyung said. "We have to use our hips for the belly dance, and there are times when we can't put all of our efforts into the performance." When one of the MCs asked, "Have you ever had an accident on stage?", Woori replied "lots" without hesitation, collapsing the studio into fits of laughter. Woori went on to discuss how the other members became aware of such a situation. "If someone takes someone else's place on stage, we can tell whether it smells or not", she revealed. In the video shown following Rainbow's confession, Woori was shown taking over Jaekyung's spot onstage, bringing fresh bouts of laughter to the audience. Well...hopefully it was just gas, right?
