The 20-year-old excitedly revealed during her UNICEF charity concert in New York about her new single.
It will be the first single of her new album for which she has already recorded 18 tracks, but she has yet to decide which ones will make the cut, reported Aceshowbiz.
If her edgy film "Spring Breakers" is of any indication, Gomez's new music is bound to be more intimate and more mature in contrast to her initial Disney darling persona.
"Through 'Spring Breakers' and experiencing so much last year it will be interesting to kind of have my fans know everything I went through, through music.
"I think for me, it was actually interesting to see that towards the middle of me recording my record, a big turn happened to me and it was incredible to see how I applied that to music because I've never done that before and it's great," she said.
