Actress Son Eun Seo recently guested on an episode of SBS's "Strong Heart" and revealed her resemblance to SNSD's Seohyun. On the show, she stated, "Before SNSD's debut,�Yoona told me that there was a member that she thought looked like me.�Turns out, it was Seohyun." Son Eun Seo continued, "I used to be a make-up model with her back in the day.�She said that she felt friendly with me because of how much I resembled one of her SNSD members. Once SNSD debuted, I found out that she was Seohyun." The studio readily agreed and claimed that she was a 100% doppelganger of the SNSD member. Be sure to check out the full broadcast on April 19th!
