Halsey on the cover of 'Billboard' magazine, March 2016.

Halsey features on the latest issue of 'Billboard' magazine, wearing a bold red lip, and rocking a variety of looks - one of the photos even features a cat!

The interview chronicles her attending Kanye West's Madison Square Garden fashion-show-slash-listening party, performing on The Tonight Show, and more.

On voting for Bernie Sanders, she says: "I'm 21 years old and it's kind of uncomfortable for me to talk about, but I'm in the 1 percent as far as my income and tax bracket. But now that I'm here, there's no amount of money you can wave in front of my face that will make me understand depriving people of human rights. While I know people in the industry who want to vote for someone who will protect them financially, I'm looking for a person who will make sure my 17-year-old brother doesn't get killed someday because he's half-black. If that means I lose 50 percent of my income every year, so be it."

On her struggle with mental health: “I had tried to kill myself. I was an adolescent; I didn't know what I was doing. Because I was 17, I was still in a children's ward. Which was terrifying. I was in there with 9-year-olds who had tried to kill themselves.”

On her love of performing: “I could be having the worst day of my life, hate my body, think I'm fat, think I suck, and as soon as I hear the first few notes of my intro, that all goes away. Everything that I hate about myself goes away when I walk onstage. That's why I cling to it so much -- it keeps me from killing myself.”
