Girls' Generation made their U.S. daytime talk show debut this morning on Live with Kelly.

The South Korean pop group performed their hit single "The Boys," which had the audience singing along. The response wowed host Kelly Ripa, who said, "I've never seen such audience participation in my life." 

During their post-performance interview, guest co-host Howie Mandel remarked at how well Tiffany spoke English. "Well, I was born in America," said the 22-year-old group member. Tiffany is one of three singers in the nine-member group who were born in the United States.

Girls' Generation has sold over 1 million albums worldwide since 2007.
