Taylor Swift fears she will end up ''lonely'', ''awful'' and ''intolerable''.

The 23-year-old singer worries she will make the ''wrong choices'' in life and push her good friends away because she they will think she is ''too good to hang out'' with them, and she is constantly concerned she will have nobody to trust when she is older.

Speaking in the new April issue of InStyle UK magazine, she said: ''What I worry about is that I never want to end up kind of a self-centred, vain human being.

''My fears circle around me making the wrong choices and messing this up for myself. I don't wanna 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.

''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. And that's why I live my life the way I live my life because I'd so much rather feel everything than end up like that.''

The 'I Knew You Were Trouble' hitmaker - who has had a string of failed relationships with stars including Harry Styles, Jake Gyllenhaal and John Mayer - revealed she had previously mapped her life out in a ''dream scenario'' but following events in her 20s she has had to change her plans.

When asked if she would like to start a family, she replied: ''I think so but I'm not sure. Like, I don't even have a master plan.

''I've thought that I did have a dream scenario before but it turns out that I change my mind and that essentially in your 20s all the puzzle pieces of your life are thrown up in the air and they just fall into whatever place and I think that's healthy.''
