Real Housewives of Beverly Hills star Yolanda Hadid, 52, who is battling Lyme disease, has marked her return to modelling by posting a sexy new Instagram shot from a photo session with top snapper Jim Jordan.

Posing in a satin corset, she writes: ''Little rusted but slowly getting back in action with @jimjordanphotography thank you @mrchrismcmillan for my new Goldie locks... #Grateful #Blessed #GoodDay.''

Yolanda's daughters, Gigi, 21, and Bella, 19, followed mum into fashion and have become big names on the catwalk, while her son Anwar, 17, made his modelling debut at Jeremy Scott's Moschino resort show in Los Angeles alongside Cindy Crawford's son Presley last month (Jun16).

Her modelling comeback isn't the only thing keeping Yolanda busy following her split from husband David Foster last year (Dec15) - she is also trying to find an ''affordable'' cure for Lyme disease, and she is planning to write about her battle with the debilitating condition in a new book to give others hope and encouragement.

"It has been my dream to write a book to share all the treatments, knowledge, and spiritual growth I have acquired," she says. "It's my Dutch foundation (roots) that gives me the balls and courage to share my raw and unedited story with the world!

"By sharing my journey in this book, I hope to offer a voice and encouragement to people who are ill and find themselves struggling while uncovering the mystery of chronic disease."
