16-year-old Justin Bieber writing a memoir

(AP) — You're never too young to write a memoir.

Sixteen-year-old Justin Bieber's book comes out in October. HarperCollins announced the pop star's memoir on Monday, saying "Justin Bieber: First Step 2 Forever: My Story" will reveal the teen sensation's "amazing journey to stardom."

The book also will include previously unseen photos for "fans afflicted with Bieber fever."

In a statement released by the publisher, Bieber says he is "excited to share just a little bit more of my world."
