US superstar Taylor Swift is the latest addition to the list of acts due to perform at the BRIT Awards on February 20th.
Swift, 23, earned an estimated $57m (£36m) in 2012 and has sold 26 million albums worldwide.
She'll come face to face with former love interest Harry Styles, whose band One Direction are also on the bill for the ceremony.
Robbie Williams, Muse, Ben Howard, Mumford & Sons, Emeli Sande and Justin Timberlake will also perform at the event, which is to be broadcast live on ITV.
Emeli Sande and Ben Howard did the double at the 2013 Brit Awards, winning two awards each, including best British male and female.
The UK's biggest night in music will be celebrated this evening as the Brit Awards come to London's O2 Arena.
Damien Hirst will have Brit Award winners seeing spots before their eyes after decorating this year's trophy with his signature design.
