America's Next Top Model Judge to Pen Book

Look out, Tyra Banks, a fellow panel member is after your spotlight!

America's Next Top Model judge - and former British supermodel - Twiggy has agreed to a six-figure deal to write a style guide for women over 40.

The 58-year-old model and actress is writing "Those Fab Forties, Fifties and Sixties," a book offering advice to older women about updating their image with the proper makeup and skin care.

Louise Moore, managing director of Penguin's Michael Joseph imprint, predicts the book will be a best-seller when it is released next June.

"Twiggy is as beautiful a woman in her 50s as she was in her 20s, and has been at the forefront of the fashion industry since she was a 1960s supermodel," Moore said.

"This book will act as a practical, essential, indispensable guide to how to rethink your style and carry it through the decades, find what suits you best, source new skincare and makeup tricks, and incorporates Twiggy's in-depth philosophy on what makes women truly stylish."
