Taylor Swift is all of 23, but she's already worrying about ending up sad and alone: "The typical Hollywood sad cliche of the poor lonely starlet with no one because she put up all these walls and didn't trust anyone," she explains.

In the April issue of InStyle U.K., the singer-songwriter goes into confessional mode again and opens up about her fears when it comes to fame and love. "What I worry about is that I never want to end up kind of a self-centered, vain human being," she tells the magazine.

"My fears circle around me making the wrong choices and messing this up for myself. I don't want end up being awful and intolerable. Alone. Laying in a marble bathtub by myself, like sad, with a glass of wine just complaining that my life ended up alone because I pushed everyone away because I thought I was too good to hang out with anybody."

Swift claims in the current issue of Vanity Fair that she's dated only two people (presumably Conor Kennedy and Harry Styles) since 2010, and in this issue of InStyle U.K., she again tries to make the argument that she's not boy-crazy. "I'm a girls' girl," she says. "I mean, there's all kinds of complicated things with having guys as friends. If they have a girlfriend who doesn't like you or things like that. So I have, like, two or three guy friends. A select few. But I have like 20-25 really good girlfriends."
