The former TOWIE star's first-ever book is available from 1 January and is described as her guide to a "healthy, happy new you."
It's no surprise Lucy has turned her attentions to a fitness and nutrition book after her huge success with fitness website Results with Lucy, which is flying high.
Lucy, 23, said: "I'm probably the happiest and most content I've ever been, but I've had to work really hard on my body and on my confidence to get here. This book is my personal journey, but it's also a diet and lifestyle plan that will help you transform your body and live a long, strong, healthy and happy life."
Lucy quit The Only Way Is Essex in order to focus on her fitness and nutrition brand, which offers personal training advice, videos, meal plans and inspiration to help users lose weight, tone up or just achieve a healthier lifestyle.
Be Body Beautiful is published by Penguin, which reveals the book contains Lucy's six-week diet and fitness plan and aims to provide a "lasting lifestyle-based approach" to health and nutrition.
The publisher claims: "Be Body Beautiful tells of Lucy's rollercoaster last few years and how she learned to take control of her body and her life. For anyone who wants to transform themselves for good, this book will be a life changing read."
Is there anything Lucy can't do?
