Taylor Swift Reveals Who Her Song Is About

'You're balancing the analytical side of your brain,' Taylor says about performing at the BRIT Awards, 'which is telling you where to go and how to go there, with the other side of your brain, which is saying 'Feel everything you're singing, and show it on your face. Feel everything exactly as you felt it when you wrote the song.'

Tay Tay definitely seemed to 'feel everything' at the BRITs when she tore off a wedding dress to reveal sexy black lingerie.

Even though Harry was getting a hate letter sung straight to his face by his lingerie-clad ex, he remained cordial after the BRITs. 'I thought her performance was really good, she looked great,' he said. That takes a lot to hold back, since he can probably recognize that 'I Knew You Were Trouble' is for him.
