SS501 Kim Hyung Joon's older cousin, Ellie Jung, recently featured for the recording of the upcoming fourth episode of 'Sweet Room'. Ellie Jung, who works as an interpreter, is said to have a very close relationship with her cousins Kim Hyung Joon and Kim Ki Bum of U-KISS. Kim Hyung Joon made an appearance on the show to gift her a special jacket he made with the help of Big Bang's stage outfits designer, Ji Il Geun. On the show, Kim Hyung Joon directly helped in coordinating Ellie Jung's outfits and watched over her throughout. MC Kim Sae Rom jokingly nicknamed her the "sister-in-law" as the two kept showing their close relationship. Ellie Jung revealed that she only prefers black and white, formal outfits because of her job as an interpreter, and had only black and white clothes in her dressing room. In response, MC Kim Sae Rom and her stylists were able to successfully give her closet an extreme makeover and helped her revitalize her fashion. The full episode is set to air on December 19th.
