Taylor Swift writing about a crash-and-burn heartbreak

(CBS) The next person who falls for Taylor Swift may want to watch out. The singer, who has been known to reference her failed romances in her music, is at it again.

Swift, 22, is currently working on her fourth album and tells Vogue that she's getting inspiration from a past relationship.

"There's just been this earth-shattering, not recent, but absolute crash-and-burn heartbreak, and that will turn out to be what the next album is about," she said.

Jake Gyllenhaal, perhaps? Although Swift didn't drop names, it's a guy from her past. The pair dated back in 2010, and reports at the time said Gyllenhaal dumped her. Bad move, if you want to avoid making it into one of Swift's break-up songs.

Swift, though, maintains that songwriting serves as a kind of therapy for her. "The only way that I can feel better about myself -- pull myself out of that awful pain of losing someone -- is writing songs about it to get some sort of clarity," she said.

When asked what she's learned from dating, Swift said, "I have red flags now." Among the dealbreakers? "I can't deal with someone who's obsessed with privacy," Swift said. "People kind of care if there are two famous people dating. But no one cares that much. If you care about privacy to the point where we need to dig a tunnel under this restaurant so that we can leave? I can't do that."

"I think I am smart unless I am really, really in love, and then I am ridiculously stupid," she admitted -- something we may have all been guilty of from time to time.

Swift famously dated Joe Jonas, actor Taylor Lautner and reportedly John Mayer. Although she doesn't divulge which songs are about whom, it's believed that her 2008 track "Forever and Always" was about Jonas and "Dear John" written about Mayer.
