He's only 16, but Justin Bieber is already releasing a tell-all about his life -- and we've got a sneak peek at some of the never-before-seen photos inside!
The book, "Justin Bieber: First Step 2 Forever: My Story," chronicles Justin's transition from boy-next-door to heartthrob to millions -- and we're told it is packed with behind-the-scenes tour photos and candid shots from his everyday life.
Check out the preview pics we got our hands on -- and see the rest in the new book, which is out today.
