The teen star who hit the top with Unchained Melody will be revealing all, whatever that might be!
What's in it?
He's signed a deal with Virgin Books for a series of biographies.
The first is called, a little unimaginatively, Gareth Gates: The Official Book.
And another is planned for 2003.
Virgin described Gareth as a "phenomenon."
But will he have enough to fill a book or will it be all Rachel S Club and hair gel?
We'll have to wait and see!
