Singer Lee Hyori clarified the rumor behind 'radio scandal.’

Hyori revealed during KBS 'Happy Together 3' aired on March 8, the truth behind the rumor with singer Rain. The rumor was from a while back when singer Kim TaeWoo called his friend Rain during his radio program, and Rain said that he slept with Hyori, not knowing that he's on air.

In 'Happy Together,' Hyori said, "Radios usually contact the stars beforehand, so the stars are aware and know that they are going to be contacted from the radio station."
