Why is One Direction so big on Twitter?

[Lexi]

where are you from???
they're a HUGE deal in the uk...they're the biggest boyband there
and in Australia and canada too....like all the girls in my school talk about them
they're pretty popular in europe as well

the only place they havent yet released their music is in the states,but they'll release their single digitally on the 13th of Feb i think so expect the radios to play it and the album comes out in march
so yeh...they'll get a wholeload more popular...ttrust me....but yeh,if you live in the US or anywhere i havent mentioned...they'll be unknown
