Korea's power couple Jang Dong Gun and Ko So Young have been double cast as new CF models for LG Electronics' "Tromm"! Ko So Young previously worked with the brand back in 2004, and was succeeded by actress Lee Na Young soon after. This time, she's back with her husband to promote the brand's #1 premium image. The two will be endorsing the Tromm washing machine's 'direct drive' motor technology. Representatives of LG revealed, "The couple was a major factor in the brand's growth this year, so we're looking forward to seeing what they'll be bringing for our washing machines." Their CF can be seen on TVs nationwide starting next month. Source + Photos: Star N News via Naver
