Ever since its premiere at the [article id="1679204"]54th Grammy Awards[/article], folks have speculated long and hard about Katy Perry's "Part Of Me," and whether its various lyrical barbs -- "You can keep the diamond ring, it don't mean nothing anyway/ In fact, you can keep everything -- except for me," in particular -- were aimed at her soon-to-be ex-husband, Russell Brand.

It would seem to make sense ... after all, Perry's no stranger to the occasional(ly brutal) kiss-off (check the Teenage Dream track [article id="1649141"]"Circle The Drain"[/article] for proof), but there's just one tiny problem: [article id="1655103"]"Part of Me" first surfaced in 2010[/article], two months after [article id="1650689"]Perry and Brand got married[/article] in India.

And while Katy has yet to speak publicly about the [article id="1676628"]pair's split[/article], she was definitely looking to set the record straight about her [article id="1679744"]latest chart-topping hit[/article] ... which most certainly isn't about Brand, no matter what you might think.

"I wrote it two years ago, which is funny because everybody is like 'God, it sounds so current,' " she told MTV News recently in Los Angeles. "And some people that I work with were like 'You should just say you wrote it a couple of weeks ago.' I'm like 'I'm not a d---, I'm going to tell the truth.' I wrote it two years ago when I was writing and recording Teenage Dream, [but] it didn't feel right on the record. I would've had to take out one of my other songs that [made the album] a nice, complete package."

And despite her denials, Perry realizes that some folks will just keep on assuming "Part of Me" is a direct swipe at Brand ... and she really can't blame them: After all, even she'll admit that there's a whole lot about the song that seems practically preordained.

"I always planned to put it out in the spring of this year, to possibly perform it at a big [awards show], but sometimes I'm like, 'Am I living in 'The Truman Show?' ... what's going on?' " she laughed. "Because I sit down and I write all these songs at once, all these emotions and feelings and thoughts, and then, like, it just feels like sometimes I'm caught in this movie where my life is paralleling my music! It seems very serendipitous, but, as un-fun as it sounds, I prepare everything. I'm overly prepared and kind of a control freak in the best of ways.
