That's right -- Justin Bieber is penning an illustrated book that will feature the behind-the-scenes story of his rise to fame.

"Every day I wake up and count my blessings. My fans have played such a large part in all of this and they help me live my dreams every day. I'm excited to share just a little bit more of my world with them through this book," says Justin. "Between the behind-the-scenes pictures and the story I think this is going to be something they can all enjoy. This is just another way for me to say thank you to my fans."

The book is due out in October and is titled Justin Bieber: First Step 2 Forever: My Story. It will also feature exclusive, never-before-seen photos of the Biebs.

Justin isn't the first teen superstar to write an autobiography -- Miley Cyrus did the very same thing in 2009. Guess he's "just being Miley!"
