Alot of you may not know who the heck are “Wonder Girls”.

FYI, The Wonder Girls (Korean: 원더걸스) are a South Korean girl group. Each of the five original members were selected through auditions. Debuting in early 2007, they became popular in the fall of that year with the song “Tell Me.” They have scored three consecutive #1 hit singles: “Tell Me”, “So Hot”, and “Nobody”. In 2008, they won two awards (“Artist of the Year” Awards) in South Korea.

The group began their entry into the American market in 2009, with lead single “Nobody”; the single became the first song by a Korean artist to enter the Billboard Hot 100. They are co-managed in the United States by JYP Entertainment and Jonas Group.

In June 2009, JYP Entertainment announced that the Wonder Girls would be joining the Jonas Brothers on the North American leg of the Jonas Brothers World Tour 2009. The company also announced that “Nobody” would be the first English single, followed by “Tell Me”, and that an English album would be forthcoming. It was later revealed that in order to concentrate on their American debut, both So-hee and Sun-mi dropped out of high school as it was not possible to attend while in the United States.
