Almost as interesting as the pre-debut photos of Korean celebrities themselves are selcas of their family members, hence, it is no wonder that pictures of two siblings related to Wonder Girls' Yeeun/Yenny, which have recently surfaced online, are rapidly gaining attention. Yeeun's older sister and younger brother are seen throwing up peace signs and blowing kisses at the camera. While the former revealed her no make-up face wearing Harry Potter-esque glasses, the latter looked adorable sporting an animal fur hat. Netizens expressed their reaction to the uncanny resemblance among the Park siblings, leaving comments like, "Even their poses are similar" and "Good looks must run in the family." In other Wonder Girls-related news, our friends at WG Spectacle are planning to make #wondergirls a trending topic to celebrate the quintet's guest appearance on the FOX TV show So You Think You Can Dance. Please make sure to join the special occasion, which will begins on Wednesday, December 9th @ 8/7 pm EST!
