Fans of the 21-year-old singer are showing their support on Twitter with the hashtag #ProudOfHalsey.
"Those of you who have tweeted me kind things, thank you for your support," the "Colors" hitmaker wrote.
"Those of you turning this into an opportunity to bully me: I'd say I hope you understand one day but I wouldn't wish this upon anyone. It was a year ago and I am growing past it and I am looking forward to the possibilities the future will bring me in having my own family."
The "New Americana" singer got pregnant during her 2015 "Badlands" tour, but the stress of traveling and overworking her body likely led to her losing her baby.
