We all know that Britney Spears is not real. She does not exist. She is a fabrication of the music industry. For the songs, a computer generated voice was created (hence the froglike sound of it in some of her songs). For the Music videos, the designers of Lara Croft were abducted and forced to create a CGI teenager. For the live tour, a complex robot is used (the snake on her back is in fact a hydraulics cable - a last minute adjustment, as an internal pipe failed, and hence they needed to bypass it externally, painting it green and letting it hiss every now and then).
To my great shame, I actually like her music, too. Sort of easy listening stuff...
