NEW YORK (AP) -- Taylor Swift's next album will be about an "absolute crash-and-burn heartbreak" she had. Swift tells Vogue magazine it helps her "feel better" and gain "clarity" by writing songs about her relationships. Of course, she doesn't name names, but she did date Jake Gyllenhaal for a few months in 2010, and he broke up with her. Swift says she now has a list of "red flags" if a relationship won't work. For example, if a guy falls in love with her based on her Wikipedia page or is threatened that she needs security, maybe puts her down or is obsessed with privacy, they're not for her. Got that? Swift is on the cover of the February issue of Vogue which goes on sale January 24.
