The singer recently shared several photos and videos where her hair was styled like her former "Hannah Montana" character and reminisced about the Disney show that helped her rise to stardom.
Cyrus played Miley Stewart, a teenager living a double life as a pop star, on the show, which aired from 2006 to 2011.
In one clip, Cyrus shows off her new look and jokes to the camera, "You know guys, it was so hard going back and forth. I decided I'll just be Hannah forever!"
"Icons only! #HannahMontana," she captioned another post.
She also shared a video singing along to the show's theme song, "The Best of Both Worlds."
Cyrus said that her former character is "punk now!"
The actor also decided to take part in the viral #10yearchallenge. "I WIN!" she captioned her post.
