A source told
People that Miley's parents left before that shot was taken. Her grandmother and her teacher were on set, "
Miley's grandmother and her teacher were there when she shot it. Annie convinced them it was going to be artistic. Her parents are mortified. They know this is a learning moment for Miley. The photo suggests that she is [naked], but she is not. She is covered by a sheet, and beneath the sheet she is clothed. Originally, she was in a flesh-colored tank top but was asked to remove it."
