Which Celeb Inspired Taylor Swift's Latest Breakup Song?

Yes, She's Written Yet Another One

Apparently, Taylor Swift hasn't been so busy chasing a Kennedy that she didn't have time to write yet another of her drippy breakup songs, so let the guessing begin as to which Swift ex inspired the new tune "We Are Never Ever Getting Back Together."

The song, from her upcoming album Red, is now available on iTunes, and, according to a report at In Case You Didn't Know.com, fans are already wondering if the song is about Taylor Lautner, Jake Gyllenhaal, Joe Jonas or John Mayer.

ICYDK.com reports that Swift, who famously has a habit of roasting her exes in her songs, didn't name names, but discussed the new tune on Good Morning America.

"This guy walks in who is a friend of my ex's and starts talking about how he's heard we're going to get back together," Swift said. "And that was not the case. So I start telling them the story: break up, get back together, break up, get back together … and I picked up the guitar and (her songwriting partner Max Martin) said, 'This is what we’re writing.'"

But a specific pair of lines from the song may be a hint at the ex she's singing about now.

"Hide away and find your peace of mind, with some indie record that's much cooler than mine," Swift sings in "We Are Never Ever Getting Back Together," which suggests her ex is also a singer, which narrows it down to Jonas or Mayer, right?

Both Jonas and Mayer have been targets of Swift musical missives in the past.

Meanwhile, as we hope the 22-year-old pop star will eventually stop writing revenge songs that make her sound like a 13-year-old girl writing in her diary, she may want to save up her best disses for future breakup tunes.

Because given her newest alleged boyfriend -- Kennedy teen Conor, son of Robert Kennedy, Jr. -- and the long history of how the Kennedy men treat women, she's going to be writing one doozy of a breakup song soon.
