Girl group Rainbow revealed their thoughts on actress Go Hyun Jung after making their short cameo in SBS's "Dae Mul". The girls revealed about meeting Go Hyun Jung, "She's got such charisma and force that we all thought she'd be cold and scary. Since she's such a huge senior to us, we were highly nervous. Contrary to what we believed, she was extremely warm and initiated conversations with us first." Regarding their cameo scene where they had to perform their famous 'ab dance,' Rainbow laughed, "We explained the dance to her once and she understood it right away. She began dancing it on the spot, even though it's not an easy dance to get right away. When she saw how surprised we were, she told us that she had seen our performance once. We were very thankful." When asked to rate Go Hyun Jung's 'ab dance' skills, they answered, "Definitely 10 out of 10. She danced it so well that it attracted more attention after that." On the topic of their acting, Rainbow admitted, "It was really fun. We didn't think we'd be able to do it properly but everyone around us helped out a lot and gave us a lot of compliments. We got so excited that we began ad-libbing our lines. The director told us, 'Half of your lines are ad-libs.' He even tried to come up with corny names for us, which we actually came up with ourselves on the spot. Should the opportunity arise, we'd love to try acting once." Source + Photo: Sports Chosun
