Country balladeer Taylor Swift says she can't sleep at night because of nightmares about ending up alone at the end of her life. The crossover songstress fears her meteoric fame will change her into an "awful and intolerable" old woman.

Swift has been accused of serial dating with a track record of 2-month flings with high profile male celebrities. The list includes John Mayer, Jake Gyllenhaal, Taylor Lautner and most recently One Direction playboy Harry Styles who she reportedly broke it off with in mid-January.

Swift admitted to Britain's InStyle magazine that her number one fear in life is ending up a lonely, wretched old lady.

"I never want to end up kind of a self-centered, vain human being... I don't wanna end up being awful and intolerable. Alone. Laying in a marble bathtub by myself... sad, with a glass of wine just complaining that (I) ended up alone because I pushed everyone away because I thought I was too good to hang out with anybody."

In a recent Vanity Fair interview Swift made waves when she directed her, "there's a special place in Hell for women who don't help other women," comment at Tina Fey and Amy Poehler for joking about Swift's love life during the 2013 Golden Globe Awards.

All in all, Taylor Swift just wants to avoid the stereotype.

"The typical Hollywood sad cliché of the poor lonely starlet with no one because she put up all these walls and didn't trust anyone. That's my fear."
