With a rather hectic schedule, Wonder Girls have been jumping from one continent to another for their promotional activities in U.S, Korea and China. On the 12th, the Korean idol sensations performed as the special guests for Jordin Sparks' concert held at Giant Center in Hershey, Pennsylvania. Held in commemoration of Founders Day, the event was a private function for Milton Hershey School students, staff and alumni with only 200 tickets awarded to the general public. Wonder Girls' official U.S. website (www.wondergirlsworld.com) recently updated behind-the-scene photos of from the Hershey's event to share the sweet experience with the public. The members are seen fooling around backstage before their performance, to which fans have left positive comments: "Yubin unni got really pretty." "Regardless of what other people say, I like Wonder Girls and I like Ye Eun noona. I like them, I like them, I like them." "I find it quite charming when Sohee glares like that." "Yubin is so pretty. Let's be friends. I will earn a lot of money and even beg on my knees. Let's be friends just for one day." "In the group picture, it looks like Sunye wore the dress backwards. keke" The girls are surely missed in Korea, but WonderFuls remain as patient as ever, awaiting Wonder Girls' return.
