Talk about a teen who's working overtime! Miley Cyrus has scored another major deal, signing a seven-figure book deal with Disney Book Group. The book will cover topics such as Miley's childhood in Tennessee to her current chart-topping success as a performer and, according to Disney, will feature never-before-seen photos, family stories and a look at the star's closet confidants. "I am so excited to let fans in on how important my relationship with my family is to me," said Miley. "I hope to motivate mothers and daughters to build lifetimes of memories together, and inspire kids around the world to live their dreams." The book is scheduled for publication in spring of next year to coincide with the premiere of the Hannah Montana movie.
