Eat your heart out, Joe, John, Jake, Conor!

A very grown-up-looking Taylor Swift graces the cover of the December issue of Cosmopolitan magazine. Cosmopolitan, known for its raunchy coverlines, went in a different (now reportedly dated) direction for Swift’s cover blurb: “Crazy for a Kennedy.”

Ouch. For a woman that just sold 1.2 million copies of her new album, Red, that cover declaration is pretty err.., mean.

And while the cover picture is obviously not super-scandalous, I think it’s the first time the now 22-year-old singer has posed next to the line “Late Night Sex.” She may sing about never growing up, but this is clearly a step in that direction.

Elsewhere in the interview, Swift talked about the things that will make her never, ever get back together with you. “I can’t deal with someone wanting to take a relationship backward or needing space or cheating on you,” she said. “It’s a conscious thing; it’s a common-sense thing. If I was in that situation, if I were them, would I be doing this to me? Would I ever do this to them? If the answer is no, then they’re not treating me fairly. I just don’t ever want to end up in a relationship that isn’t fair ever again.”

Besides the guy drama, Swift also talked about her love philosophy, and how that ties in with the themes of Red. “I have a chalkboard in my house in L.A., and every week, I’ve been writing a new lyric on it from the record just to figure out which ones pop out to me, which seem most important,” she told the magazine. “There’s a song that’s the first track on the record, and it says, ‘Love is a ruthless game unless you play it good and right.’ That’s been my whole philosophy on love this whole time anyway. “

Celebrity guys, consider that your warning.
