Yesterday, we reported the unfortunate news that actress Song Ji Hyo was rushed to the emergency room after an allergic reaction which sprung from her receiving an IV drip due to her fatigue from continuous filming. Just two days later, it's been reported that the 'Gyebaek' actress is back in the hospital due to her constantly rigorous schedule. Although the hospital recommended taking an ample amount of rest, she returned to the set of 'Gyebaek' on the evening of the 17th and continued filming for two straight days without rest, which resulted in staff rushing her to the emergency room once again on the morning of the 19th due to extreme fatigue. "Although the hospital recommended rest when she was hospitalized for the first time, she returned to the set after discussions with the producers," said a representative."Due to the continuous filming schedule, she had no choice but to return to the hospital." The actress has already cancelled her plans to participate in this week's taping of 'Running Man', a variety show in which she is a fixed cast member. However, her filming for 'Gyebaek' will continue. Source: Star Today via Nate
