Wonder Girls have been absent from the entertainment scene for quite a while now, so what could they possibly be up to? Recently, Yenny of Wonder Girls tweeted, "as u all know, we're in Korea now !! and i'd like to keep what we're doing here as a secret ;)" Honestly, I didn't even know that they were back in Korea since they have been on the down-low for such a long time! However, referring back to Yenny's mysterious message, what could the Wonder Girls possibly be doing in Korea and in such a secretive state? Possibly a Korean comeback? I'm sure fans are anticipating that. Stay tuned as we bring you updates on their U.S. debut!
