Can anyone say Pop phenomenon / teen mania?
Boyband of the moment One Directon show up at NBC's Today Show atop a double-decker open-top red bus to perform debut single "What Makes You Beautiful" for a huge crowd of ecstatic American fans.
Needless to say, the boys are already HUGE stateside - their album release has been brought forward thanks to overwhelming demand, the single's blowing up on radio and they're scheduled to perform on iconic US show Saturday Night Live.
