Miley Cyrus is trying something new.

The singer has a new single coming out May 11, a love song for her fiancé Liam Hemsworth called Malibu. It's a part of her sixth as yet untitled studio album coming out later this year, and it's a different style for the singer.. And But it's not the only thing about her life that has changed, as she explains in a new Billboard cover story.

"(People are) going to talk about me if I come out of a restaurant with Liam," Cyrus, 24, told the magazine about putting her love into her music. "So why not put the power back in my relationship and say, 'This is how I feel'?"

Cyrus and Hemsworth got back together last year after breaking up in 2013, and she says that it wasn't like flipping a switch.

"I needed to change so much. And changing with someone else not changing like that is too hard. Suddenly you’re like, 'I don’t recognize you anymore,'” she said. "We had to re-fall for each other."

Her recent changes include giving up smoking marijuana for the past three weeks, though she did not say whether it'd be a permanent decision.

“I haven’t smoked weed in three weeks, which is the longest I’ve ever (gone without it),” she said. “I’m not doing drugs, I’m not drinking, I’m completely clean right now! That was just something that I wanted to do.”

"But if anyone told me not to smoke, I would have not done it," she added. "It’s because it was on my time. I know exactly where I am right now."

Cyrus, who campaigned for Hillary Clinton in the fall and posted a tearful Instagram after the election results came in, explained that her album is also about trying to reach those who don't agree with her.

“I have to ask myself, ‘How am I going to create real change?’” she says, “and not just ­(expletive) preach to the choir anymore. ... This record is a reflection of the fact that yes, I don’t give (an expletive), but right now is not a time to not give (an expletive) about people. I’m ­giving the world a hug and saying, ‘Hey, look. We’re good -- I love you.’ And I hope you can say you love me back.”
