NEW YORK (AP) — He's only 17, but pop sensation Justin Bieber is back with his second book.

HarperCollins announced Tuesday that it will publish "Justin Bieber: Just Getting Started." The book is described as "the second official photographic book" from the multiplatinum-selling superstar.

The company says it will be released worldwide in September.

The new book promises a look inside the world of Bieber: touring the globe, making a movie and recording his new album.

His first book, titled "First Step 2 Forever: My Story," was published in October 2010. It has sold more than a million copies in 25 languages.
