The "Superior Sisters," SNSD / Girls' Generation member Jessica and f(x)'s Krystal have finally appeared together on Star King. When young magician Chu Seung Ho asked the sisters, "Which one of you think is the prettier one?" Jessica showed her warm sisterly love by replying, "Krystal is the prettier one." Although it was Krystal's first time recording for Star King, Jessica helped her little sister out by easing her nervousness and sharing many laughs together. http://www.youtube.com/watch?v=9K1WBNHXuCw
