The current members are Sunye, Yeeun, Sohee, Yoobin, and Haelim. Former members include HyunA (now in 4Minute) and Sunmi. HyunA had left the group due to health issues, and Sunmi had left to go back to study in Korea. However, Sunmi still has the option to come back to the Wonder Girls.
The Wonder Girls have many hit songs like Irony, Tell Me, So Hot, and Nobody. They sparked a dance craze in Asia, (mostly Korea) with their hit song Tell Me. The Wonder Girls have hit the U.S. and have successfully entered the U.S. market. They are the first ones to do so. The Wonder Girls have toured with the Jonas Brothers, opened for Justin Bieber, and been on the Wendy Williams show and So You Think You Can Dance. Nobody is also a hit song in other foreign countries.
The Wonder Girls will have their own tour this summer with 2PM as their opening act. They will also release their mini album in May, and release a brand new english album in July.
