Video performances from 2009 BRIT Awards taking place on February 18 at London's Earls Court have arrived. Lady GaGa, U2 and Girls Aloud were some of those making live appearances at the annual event.
Lady GaGa took the stage with electronic dance music duo Pet Shop Boys. Also joined by The Killers' vocalist Brandon Flowers, they did a medley by performing several songs, one of which was Dusty Springfield's 1989 single "Nothing Has Been Proved", and compiled them into a single piece of music.
U2 sang their new track "Get On Your Boots" from their upcoming twelfth studio album "No Line on the Horizon". Girls Aloud delivered song "The Promise", which made them winning Best British Single, while The Ting Tings and Estelle made a collaboration, singing "Shut Up and Let Me Go", "American Boy" and "That's Not My Name".
Other performers at the awards were Take That, Coldplay and Kings of Leon. Take That entertained audience with "Greatest Day", Coldplay performed "Viva La Vida", and Kings of Leon played "Use Somebody".
