Cyrus is the daughter of US country singer Billy Ray Cyrus
Miley Cyrus, teenage star of Disney's Hannah Montana TV series, has signed a book deal to tell her life story.
The 15-year-old's memoir will focus on her relationship with mother Leticia, according to the Disney Book Group.
"I am so excited to let fans in on how important my relationship with my family is to me," said Cyrus.
She said she hoped "to motivate mothers and daughters to build lifetimes of memories together and inspire kids around the world to live their dreams."
The book, to be released next spring, will feature previously unseen photos, family stories and "a look at her inner circle of loved ones".
The teenage pop star, whose father is US country singer Billy Ray Cyrus, topped the North American box office in February with a 3D film of her 2007 tour.
