He's only 16, but Justin Bieber is already working on his life story.

USA Today reports that HarperCollins is releasing the teen idol's official illustrated memoir that will tell the behind-the-scenes story of his journey to superstardom.

Justin Bieber: First Step 2 Forever: My Story - due out in October - also will feature never-before-seen shots of the Canadian teen. Bieber, who was raised by a single mother, was first noticed after posting a series of videos on YouTube. Scooter Braun, who later became his manager, later helped him nab a recording contract with Island Records.

Earlier this year, Bieber's album My World 2.0 soared to the No. 1 spot on the Billboard charts within a week of its release.
