Today is the birthday of sexy Wonder Girls' rapper Yubin! She turned 21 (22 in Korea) today. On her minihompy, the rapper wrote to herself, "Happy birthday to me, Happy birthday Yubin. Hello 22, nice to meet you." Her fellow members also wished her a happy birthday on Twitter. Yenny wrote, "Happy birthday Yubin !! We're having a great day right?!! Haha :)" Mimi wrote, "Happy birthday!!!!!!!!!!!!!!!Yubinyong!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!she's sleeping..................." Does Mimi get really excited on Twitter or what? And lastly, Leader Sun said, "Today is happy SUNDAY. And ALSO Yubin's B-day! yay~~ I would like everyone to tell her something about it! :)" As we reported earlier, Yubin recently went back to Korea with Sohee to celebrate Chuseok with her family but she has returned according to this tweet from the birthday girl herself, "today's my B-Day!!! I'm in Central park with Yenny~ hhhh" Hope she had a birthday to remember in the city that never sleeps! Also make sure to check out WG Spectacle Forum.
