Think you know everything about Justin Bieber? Well, fans of the 16-year-old pop star will learn much more when HarperCollins releases his official illustrated memoir, "Justin Bieber: First Step 2 Forever: My Story."

In a press release, Bieber said, "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. 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, due in October, will chronicle Bieber's beginnings in Stratford, Ontario, his work with his manager Scooter Braun, his landing a record deal with Usher and his success in pop music thanks to hits like "Baby" and "Somebody to Love."

"Justin's adoring and devoted fanbase that started on YouTube now follows him to packed concert halls around the world," Susan Katz, president and publisher of HarperCollins Children's Books, said. "He is a force in the music industry and we are incredibly excited to be publishing this photographic memoir of his amazing journey."

"This is a real coup for us and we are very excited about adding Justin to our autumn program," Harper nonfiction senior commissioning editor Anna Valentine added. "Justin is the hottest star of the moment and this book will be the perfect gift for his millions of fans worldwide."

Bieber also announced on Twitter that he's hard at work on a few other projects. "New Vids comin from both MY WORLD and MY WORLD 2.0 in the coming weeks!" he wrote. "Proud of these albums, proud of the music, and thankful 4 ur support."

The singer, who is currently on tour, is also slated to make his network TV acting debut on "CSI" this September. "CSI premieres on Thursday, Sept 23rd on CBS ... and I told you I was a BAD MAN!!" he tweeted, along with a photo of him being arrested on the show. According to CBS, he plays Jason McCann, a "troubled teen who is faced with a terrible decision regarding his only brother — a decision that leads him into an explosive confrontation with the CSIs."
