As many of you know already, Girls' Generation will guest on two major American talk shows, CBS's 'The Late Show with David Letterman' tonight on January 31st and ABC's 'Live! With Kelly' on February 1st.

Earlier this afternoon, the ladies arrived at the Ed Sullivan Theater to film their segment on 'The Late Show with David Letterman'. Hundreds of fans eagerly awaited their arrival and it was well worth the wait as the girls greeted the fans while exiting the coach bus. The coach bus itself featured advertisements for Girls' Generation and their latest release, "The Boys".
