The Nashville act, whose record sales in Britain and Australia eclipse those in their home country, scooped the international group and international album categories at Wednesday's BRITs ceremony.

In the singles charts Lily Allen held the top spot with "The Fear", while American singer Lady GaGa was steady in second place with "Just Dance".
