Forget [article id="1593867"]Drew, the inspiration for "Teardrops on My Guitar,"[/article] or [article id="1599032"]Joe Jonas, who sparked "Forever & Always."[/article] When Taylor Swift sat down to write [article id="1645042"]her latest hit song, "Mine,"[/article] she had a different dude, who remains a mystery, on the brain.

"I was reflecting back on a boy I liked at a certain time," she told Rolling Stone about the tune, which will appear on [article id="1646008"]her forthcoming album Speak Now[/article]. "The song is about what it would be like if I actually let my guard down."

Speak Now comes out on October 25, and Swift is bracing for the onslaught of craziness that will ensue as the drop date nears. But she loves the chaos. "I'm obsessed with being busy. It's hectic and nonstop," she said. "But I'm so ready."

What Swift wasn't ready for was "Mine" [article id="1645097"]leaking online earlier this month[/article]. After its early arrival, the song was rushed to radio and iTunes and subsequently debuted at #3 on the Billboard Hot 100. Swift admits that while she appreciated the overwhelmingly positive response to the track, she in no way was expecting it to be released prematurely.

"[My manager] said, 'I don't want you to panic.' And I said, 'The song leaked, didn't it?' " she said. "I turned on my phone and there were texts saying, 'Congratulations.' A leak is so out of my comfort zone, but it ended up good in the end. It made me so emotional that I started crying."

The video for "Mine" [article id="1646189"]premieres Friday (August 27) at 8:30 p.m. ET[/article] on MTV.com, VH1.com and CMT.com.
