She's only 15 years old, but Hannah Montana star Miley Cyrus has written a book about her life so far and her dramatic rise to fame.
Despite being so young, the star of the hit TV show has also had a number one film and two best-selling albums, so she says she's got plenty to say!
You'll have to wait to read it though, it's not due out until spring 2009.
"It's finished but you've got a long process of editing and all that kind of stuff, so it takes a while," she said.
The book is also expected to feature loads of photos of Miley's family, including her dad Billy Ray Cyrus, who plays Hannah Montana's dad and is also a famous country singer.
Meanwhile, Miley has also said she wants to do another series of Hannah Montana.
"Hopefully I'm going to go into season four, but we're not sure so right now we're just getting through season three," she said.
