On Wednesday, Dec. 9 (8:00-9:00 PM ET live/PT tape-delayed), Season Eight AMERICAN IDOL winner Kris Allen and pop sensations Wonder Girls will take the stage. Allen will perform his newest single, “Live Like You’re Dying,” and Wonder Girls will sing their hit song, “Nobody,” before America’s vote is revealed and Cat Deeley names the six dancers who will perform in the following week’s finale.

Pop sensation Wonder Girls sold over 30,000 copies of their debut single “Nobody” during the week of October 11 earning them the No. 76 position with a bullet on the Hot 100. This is the first time ever a music group from South Korea has debuted on the Billboard Hot 100 singles chart. Already a hit in Asia, the Wonder Girls are striking a chord with a young U.S. audience, having just completed their first U.S. concert tour with the Jonas Brothers.
