Justin Bieber: 'It's a Photo Book, Not a Memoir'After back-to-back reports that Justin Bieber will star in a 3-D movie about his life and write a memoir along the same lines, the singer took to his Twitter to clear something up: No, he's not doing anything like an autobiography quite yet.

"It isn't a memoir ... I teamed up with this amazing photographer Robert and he has been taking pictures behind the scenes from before the tour," Bieber wrote. "So the book will include all those pics and I'm going to tell the story of all that led up from rehearsals until the first night of the tour. Pretty excited about it and think everyone will enjoy the story and the pics."

And yes, the Biebs, 16, concurs that maybe it's not quite time for his life story yet: "We can all agree I'm a little too young to write a memoir."
