"My T-shirt says, 'I Should Have My Own TV Show,'" Cyrus noted of her audition tape ensemble, before lip-syncing along with her younger self.
In the tape, Cyrus can be heard singing her tune "Beach Weekend," which included the lyric, "Trying out our brand new bikini. Maybe drive a few boys crazy."
Cyrus laughed listening to the line, quipping, "[I was] always a little controversial, from the beginning."
The "Malibu" singer also got a kick out of her 12-year-old self's response when one of the producers in the audition room asked if she'd already been signed to a music label. Cyrus confidently declared, "No, but it is going to happen!"
Cyrus ended up starring in the popular Disney Channel series from 2006 to 2011.
