Back when rapper Yoobin joined the Wonder Girls in 2007 for their Tell Me comeback, she gained a lot of popularity and fan love. Of course she's still got much love from the fans but many are worried about her recent weight loss. In the Tell Me video she's quite skinny, almost stick skinny, and received both positive and negative reviews about her figure. In their So Hot and Nobody comebacks, many people had noticed that Yoobin had put on some extra weight and was looking quite healthy. Yet again, people had mixed feelings on the matter. As the girls begin to prepare for their U.S. debut, it seems Yoobin has undergone yet another transformation as many Korean netizens are worried that she's lost too much weight too quickly. Fans have been saying things like, "She used to look so healthy...now her face looks pale." or "She's almost as skinny as Sunmi now..." But is the weight loss necessarily a bad thing? Admittedly she does look a bit tinier but it's all about what she wants. Whether its due to the recent hard work or whether it was forced, Yoobin still looks pretty regardless. What's a few pounds on a scale anyway? 2007: 2008: 2009:
