It was a late night and early morning coup for K-Pop superstars Girls' Generation as the girl group made their American television debut on two of the most popular talk shows in the U.S.
Starting with the "Late Show with David Letterman" on Tuesday night the nine-girl group performed the English version of their new hit single 'The Boys'.
And the next morning the group dropped by early morning talk show "Live! With Kelly" to the perform the same routinebut sporting different outfits.
Fans hope the appearances will help other Korean pop artists crack the notoriously tough U.S. music market.
