Tony An expressed amazement at the beauty of this one particular Girls' Generation member!

The member who stole Tony An's heart is maknae Seohyun who guested on the January 5 broadcast of 'Lipstick Prince'. Tony An's task was to apply eye shadow on Seohyun; however, he was unable to properly carry out his given duty because he was left awestruck by her incredible beauty.

He first commented, "Your skin is amazing. Honestly, nothing needs to be done because it's so nice." He then added, "I always thought that you were the prettiest in Girls' Generation."

Heechul, who was watching the situation from another room, jokingly commented, "That's because no other Girls' Generation member has guested on the show yet."
