Looks like Rainbow's Jae Kyung has a new fan in JYP / Park Jin Young. On KBS2TV's 'Sweet Night' Jae Kyung put on a very sexy dance for the participants of the show. This impressed everyone, but none more than Park Jin Young who couldn't keep his jaw off the floor. He also commented on how he was surprised with her talent as well as her fine physical shape. I don't think anyone could argue with him on that, she's so hot.
