While Taylor Swift is known for writing about her real-life loves, she typically keeps specific names to herself. But in a new interview, the singer reveals a major clue about the fella who inspired her dubstep-infused Red single "I Knew You Were Trouble."

In classic Swift form, she never actually says Harry Styles' name while addressing her performance of the song at the Brit Awards last month. She does say, however, that an ex was in the room when she took the stage, tore off her white gown and got sexy in little black shorts during the February broadcast. It just so happens to be that Styles and the One Direction guys attended that awards show.

"Well, it's not hard to access that emotion when the person the song is directed at is standing by the side of the stage watching," Swift told the U.K.'s The Sunday Times, according to OMG! Yahoo. "You're balancing the analytical side of your brain, 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.' "

The performance came in the same month she took the stage at the Grammy Awards. At that show, she performed "We Are Never Ever Getting Back Together" and got fans buzzing when it sounded like she adopted a British accent during the spoken-word part of the tune.

Despite the fact that their romance ended months ago, the pair have continued to make headlines. Swift and Styles first heated up the rumor mill during a spring fling last April. By December they started up the gossip again when they were photographed together at New York's Central Park Zoo. Then, after being spotted around the globe together, they reportedly called it quits over the holidays while on vacation in the British Virgin Islands.

The 23-year-old singer recently addressed everyone's interest in who she is singing about in an interview with Vanity Fair. "For a female to write about her feelings, and then be portrayed as some clingy, insane, desperate girlfriend in need of making you marry her and have kids with her, I think that's taking something that potentially should be celebrated — a woman writing about her feelings in a confessional way — that's taking it and turning it and twisting it into something that is frankly a little sexist."
