Entertainment Music 'I'm Completely Clean!' Miley Cyrus Talks Drug Use and Having to 'Refall' in Love with Liam Hemsworth "I'm not doing drugs, I'm not drinking, I'm completely clean right now!" Miley Cyrus says By Karen Mizoguchi Published on May 3, 2017 11:45 PM Share Tweet Pin Email Miley Cyrus says she’s “evolving” — and part of her newfound growth has been giving up marijuana. “I haven’t smoked weed in three weeks, which is the longest I’ve ever [gone without it],” the famously pro-pot 24-year-old singer revealed in her new Billboard cover story. “I’m not doing drugs, I’m not drinking, I’m completely clean right now! That was just something that I wanted to do.” Cyrus said she has grown out of, what she called, her Dead Petz phase — referring to the psychedelic 2015 album that saw the star cover her face with glittery liquid for the cover. Brian Bowen Smith/Billboard Now, Cyrus is in a different place, even dropping new music: a love ballad for her fiancé Liam Hemsworth called “Malibu.” The singer explained the meaning of the upcoming first single off her yet-untitled album, revealing to Billboard that the pop-rock song — which is slated for a May 11 release — is “unlike anything she has recorded before.” Cyrus sings: “I never would’ve believed you if three years ago you told me I’d be here writing this song.” Brian Bowen Smith/Billboard After ending their engagement in 2013, Cyrus and Hemsworth, 27, rekindled their romance in early 2016, and after writing “Malibu,” she admitted they needed to “refall for each other.” Brian Bowen Smith/Billboard On pouring her heart out in the lyrics, the former Disney Channel star shared that the song was created during an Uber ride to The Voice set, when she was a season 11 coach in late 2016.

So why not put the power back in my relationship and say, ‘This is how I feel’?” Cyrus explained why she was inspired to pen the song. Following her breakup, she was “so immersed in work” to find herself again. “I needed to change so much. And changing with someone else not changing like that is too hard,” Cyrus recalled. “Suddenly you’re like, ‘I don’t recognize you anymore.’ We had to refall for each other.” Brian Bowen Smith/Billboard These days, Cyrus shares a Malibu property with Hemsworth – and their seven dogs, two pigs and two miniature horses. Hemsworth bought the property in 2014 before Cyrus moved in, and now it’s where she built Rainbow Land, the boho recording studio where she has been fine-tuning her forthcoming sixth studio album.
