2AM's Jo Kwon has intrigued fans once again with new details on Brown Eyed Girl's Ga-In's kiss scene with B2ST's Yoon Doojoon. Ga-in guested on the latest episode of KBS 2TV's 'Secret', only to have the story of her kiss scene NGs with Doojoon from 'All My Love' revealed on television. Jo Kwon came on as a surprise witness of the incident, and explained, "When we were filming the sitcom together, Ga-In acted without NG's when she was acting with other female actresses; but for some reason, she always had a lot of NG's when she was acting next to male actors. In particular, she had a ton of NG's during her kiss scene with Yoon Doojoon." Ga-in, who seemed surprised by the subtle accusation, explained, "Because I am a woman, too, I get nervous when acting with male actors. I even got nervous when I was acting with Kim Kap Soo senior," drawing laughter in the studio. Be sure to check out the full story on 'Secret', which will air on Saturday, October 29th.
