Jaejoong and Wang Jihye went head to head in a karaoke singing battle on the September 8th episode of�SBS drama, 'Protect the Boss'. Recently at one Kangnam karaoke, Cha Moo Won (Jaejoong) and Seo Na Yoon (Wang Jihye) each sang two of their favorite songs. Wang Jihye was first to grab the microphone and sang Baek Ji-Young's "Don't Forget Me", shouting in a comical way. She also sang Jin Joo's "I'm Alright" along with the dance moves while wildly shaking a tambourine. While filming her scene at the karaoke, fellow cast members Ji Sung and also staff members praised and commented, "Wang Ji Hye's singing scene is bound to make headlines and the drama program ratings are expected go up." Jaejoong also added, "Wang Jihye's comical singing skills are the best of the best," giving her a thumbs up and continuing, "Lately a lot of people are asking about her and are curious as to who she is ...�there are people who are saying she looks different from her cold image and in the drama she shows a cute side and some people are calling me asking to introduce them to her." In response to this comment, Wang Jihye replied with excitement and laughter, yelling, "Call!" making people on the set burst with laughter. After Wang Jihye's performance, Jaejoong showed his own vocal talent. He sang Shin Sung Woo's "Suh Shi" and Sung Shi Kyung's "You Were An Impression", which made the production staff speak highly of him saying, "He certainly is Korea's top singer."
