The 25-year-old star, who dated Harry Styles, Jake Gyllenhaal and Taylor Lautner in the past, said she is interested in love only as a writer, reported Contactmusic.
"It seems like when I moved to New York love and heartbreak and the themes that used to be main factors in my music kind of faded to the background.
"Of course, love is still very interesting to me as a writer," she said.
The 'Shake it Off' hitmaker slammed people who mocked her for writing about her personal life said the criticism came to her because she is a girl.
"That joke is so old and it's coming from a place of such sexism," she said.
