She went on: “That was very important to me that music stays the priority for me and for my purpose, and so having this microphone is so representative of not just the music but using your voice.”
Cyrus also showed off the doll to fans on Instagram, as she teased a look at her own Barbie collection before adding the cute replica of herself to the haul.
She added in the caption for the Instagram video: “Barbie represents a personal dream of mine. She’s something I’ll never outgrow as she evolves with me.
“When I was little, I braided her hair and changed her outfits. As an adult, I treasure my collection I never take out of the box.
“Holding my Barbie in my hands is a true full-circle moment. Now you have a little piece of me, and every time you hold her, I hope you’re reminded that I’m rooting for you to chase your own dreams too.
“My Barbie, dressed in custom Alaia for Golden Burning Sun, is available now.”
Fans were quick to comment on Miley’s Instagram post, with one writing: “I NEED THIS OMG!”
As another called the doll “the coolest Barbie EVER!!!!”.
And a third pointed out: “Only legends have a Barbie.”
While someone else begged: “Someone buy me a Miley Barbie!”
A press statement announcing the release of the doll explained that the toy “celebrates the transformative sound and cultural footprint she has made as a musician, actress and advocate for self-expression”.
The Miley Barbie is on sale now for about US$60 ($105).
