Actress Park Shin Hye came in second with 1,253 votes (31.3%) while actress Sung Yuri came in third with 143 votes (3.6%).  Since first appearing in the entertainment world, all three female celebrities look essentially the same, so they're receiving a lot of acclaim for their pretty, unchanging facial features.

Following the top 3 were Han Hyo Joo, Kim Tae Hee, and f(x)'s Sulli.
