Katy Perry Gets Over A Bad Boy On Leaked Track

Demo for the Jessie James tune hits the Net shortly after Russell Brand files for divorce from Perry.

Katy Perry and Russell Brand have been keeping low profiles since Friday's divorce announcement, but on a brand-new song that just hit the Net, Perry sings about falling for the wrong guy.

The song, which Perry co-wrote, is actually a demo version of the Jessie James track "Bullet." While the song has many country music flourishes thanks to twangy guitars, the lyrics — minus references to cowboy boots and country accents — work for Perry. She opens with the lines: "My mama warned me about boys like you/ It's the reason I wear these high-heeled boots/ And let me give you a little piece of advice/ My papa packs heat and he won't think twice."

And the song's big chorus is signature Perry. On the sing-along refrain, Perry belts out, "I'm a bullet and I'm headed/ Straight for your heart/ Be careful what you start/ I'm a bullet and I'm headed/ Straight for your heart/ It's gonna leave a mark."

Although the song eventually landed on James' 2009 self-titled debut, the timing of the leak coincides with the news of Perry's split from comedian Brand after a little more than a year. Brand was spotted in his native England on Saturday, one day after the news broke of their breakup, while Perry, who has yet to speak about the split, is slated to perform at two concerts this month: one on January 19 in Jakarta, Indonesia, and another on January 22 in Manila, in the Philippines.

When MTV News spoke to some experts about Perry and Brand's breakup, they noted that the divorce didn't come as a surprise to them.

"From the get-go, I thought they were a sort of odd, mismatched pair," David Caplan, a celebrity news editor who has worked at publications including People and Star, told us. "She's so glamorous, pop and sexy, and he is diametrically not like that. He's a nice and funny guy, and from my encounters with her, I found her to be funny, have a sarcastic edge and a blast, but they weren't a match. Plus, she's more of a partier than he now, so their lifestyles were at odds."
