Kelly Osbourne is the child of one of the best documented – and least ordinary – families in Britain and life under the spotlight means she has had to learn from her mistakes the hard way. Fierce takes us from Kelly's first period to her first night in Chicago . From depression and dealing with alcohol and drugs, to coping with the ultimate embarrassing dad, this book is totally honest and totally Kelly.

Including advice from leading organisations and experts in their field, fashion tips, musical pet hates and even Kelly's awkward fifteen-year-old photos, this book combines exclusive insights into Kelly's own transformation from tomboy to gorgeous grown-up, with secrets, tips and spot-on suggestions to help other girls through the minefield that is growing up.

Fierce is an inspiration to anyone struggling to work out who they are, what they want to look like and what's right for them. It will be your best friend in book form.
