Celebrity books - seriously?

So here's this: "According to the Hollywood Reporter, Spears is currently in discussion with a division of HarperCollins about writing a novel. The plan is for Spears to write a "roman à clef", similar to Lauren Conrad's 2009 book and subsequent series LA Candy." (The Guardian)

And here follows my question: Do we really need another celebrity trying her hand at writing? As if the navel-gazing of star autobiographies (hardly any of which is actually penned by the celebrity in question him/herself) isn't enough, the belief that anyone who can decently sing into a microphone or cry convincingly in front of a camera also needs to write a novel eludes me. Why, oh why would you think so? And let's face it, even though Lauren Conrad's books sold well, they are not really worth their money. Just my humble opinion but yes.... So, Britney, please don't do it! You've got enough on your hands raising your kids and producing your records. As my grandma used to stay: Cobbler, stick to thy last.
