Taylor Swift at the Brit Awards 2013 | Pictures

Taylor Swift attended the Brit Awards in London today in a dramatic see-through black gown by Elie Saab. Taylor will be singing her new "22" single tonight, but everyone's eyes will most certainly be on any interaction she has with ex-boyfriend Harry Styles, who will be performing his charity single with One Direction, "One Way or Another," at the event. Taylor raised some eyebrows when she allegedly mocked Harry during her Grammy Awards performance earlier this month, but her former beau has brushed off the rumors, calling it "a great Taylor Swift performance." She'll have bigger things on her mind tonight as she is up for the best international female solo artist award against Rihanna, Lana Del Rey, Cat Power, and Alicia Keys.
