This southern 16-year-old is ready to take on Manhattan! Miley Cyrus showed off her grande Louis Vuitton Speedy bag, BlackBerry, and signature waves as she left her hotel for a spot on "Good Morning America." The very adult teen sensation sat down with Diane Sawyer to chat about "Hannah Montana: The Movie."

The Glamour cover girl talked about the smoke and mirrors of magazine photo shoots. Then Cyrus referred to herself in third person when it was time to get up and dance to her song, "Hoedown Throwdown," saying, "Miley's gotta take her big shoes off!"
