Lee Dong Wook was unable to avoid a question about his kiss scene with Girls' Generation member Jessica on his first day as MC for 'Strong Heart'.

On the April 10th broadcast of SBS's 'Strong Heart',�CNBLUE's frontman�Yonghwa shared a story behind his kiss scene on 'Heartstrings'.

Lee Dong Wook tried to protect the guest by saying that Jung Yong Hwa had no ulterior motives in kissing the actress when it wasn't specified in the script, unlike his close friend Lee Jin Wook who, "Really likes kiss scenes."

Lee Dong Wook was able to get a lot of laughs with his comment, but Shin Dong Yup was quick to silence him by asking, "How was your kiss scene with Jessica," to which Lee Dong Wook was unable to offer a response other than a sheepish smile as he seemed quite surprised by the question.
