The 18-year-old star - who has been named as the worst celebrity influence for the past two consecutive years - admitted she is happy to make mistakes in her life because if she didn`t, she would never learn anything. She said: "I mess up - there you go! But if you live your life trying to be perfect, you don`t really live your life ever, because you don`t really make any mistakes and at the end of your life you won`t be very smart or wise." The actress-and-singer - who was blasted last year when video footage was leaked of her inhaling a substance called salvia through a `bong` device - also explained she is keen to step away from her public persona and show how serious she is about her music career. Miley added to the Australian Daily Telegraph newspaper: "I don`t lip-sync. I would rather someone say I say like c**p, than have people see me lip-sync. "I want to show people who I really am, more than just what they see on TV. It`s all about the music."
