On the September 28 episode of 'Radio Star,' Ga In revealed that she is in the process of bringing suit against the people who spread false rumors that she starred in a sex tape. 

When the MCs asked her about the touchy topic, the idol answered, "It's okay now. I think many people could have mistaken [the person in the video for me]."

Ga In further explained, "When the rumors blew up, I was en route to Paris. The news had blown up about an hour after I got on the plane. I got off the plane without knowing anything. What shocked me most was the video clip I saw when I checked the messages on my phone. It was a clip my agency sent to me for clarification. What I regret about that moment is that I played the video without knowing the full situation. I was so shocked. I turned it off immediately. It was so ridiculous that I just thought, 'What the heck is this?' I'm currently in the middle of a lawsuit but it would feel iffy even if I won and got some money. I want to donate this money somewhere. So I hope that I win a lot of money [in this case]."
