It's A Battle (Of The Exes) At The BRIT Awards 2013
One Direction and Taylor Swift hit the red carpet at the music awards show.
Tensions are normally high between the nominees at the BRIT Awards, but 2013's ceremony may have taken the cake.
Swift, 23, sexed it up in a high-slit gown on the carpet before stripping down -- quite literally -- for her performance of "I Knew You Were Trouble."the Grammys?
Not really -- but the singer did show her former beau just what he was missing.
For her performance, Swift wore what looked to be a white wedding gown before ripping it off to reveal a little black lace romper underneath.
However, Styles also "won" in his own way when his band took home the BRITs Global Success Award, while Swift lost out her chance for an award for International Female Solo Artist to Lana Del Rey.
During the show, Styles also took the stage for One Direction's mash-up of "One Way or Another" and "Teenage Kicks."
Other celebrities who performed included Emeli Sande and Justin Timberlake, who won the crowd with his new track, "Mirrors," off his upcoming album.
