Miley Cyrus to write autobiography

Teen star Miley Cyrus has agreed a deal to write her autobiography.

The 15-year-old has signed a seven-figure contract with Disney Book Group to pen her life story, reports People.

The memoir will follow the actress/singer from her childhood in Tennessee to international stardom following the success of Disney show Hannah Montana.

It will mainly focus on her relationship with mum Leticia, but will also discuss her father, country singer Billy Ray Cyrus.

She said in a statement: "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, which will include previously unseen family photographs, is scheduled for release next year.
