Watch this duo perform some of Joan's greatest hits
For Miley, transitioning from Disney pop star Hannah Montana to performing as herself hasn't been as difficult as the media would make it seem. "Everyone likes making the transition real hard," she says. "Joan said, 'You've got to do what you said, and you've got to be honest.' It's not about how far I can push things so people will believe that I'm not Hannah Montana anymore. You just make the music that you love, and because I'm growing up, so does my music. It's not about making a statement."
