HANNAH MONTANA star Miley Cyrus has defended her memoir against critics insisting she's too young to publish her life story at age 16.
Cyrus speaks out about growing up in the spotlight, being tormented by bullies and her break-up with Jonas Brothers singer Nick Jonas in her new autobiography Miles to Go.
And though the teenager admits she still has many lessons to learn, she is convinced sharing her many experiences will be eye-opening for her young fans.
She tells America's Glamour magazine, "People are like, 'You're 16, why would you write your life story?' But in the business I'm in, I have lived a life that some people who are in their sixties haven't lived. I've gone through a lot and seen a lot. But I still have a lot to learn."
