Timeless beauty, Modern allure, these are the terms luxury brand Gucci uses to describe Monaco's equestrian royal princess Charlotte Casiraghi.

An accomplished equestrian and a long-term client of the house of Gucci, Casiraghi has featured in a series of images for the brand's new Forever Now campaign. The complete campaign visuals will be shot over a period of two years by four acclaimed photographers.

The inaugural shot for the campaign was taken by lensman Peter Lindbergh in a stable and showcases the princess in a green and red stripes outfit.

Charlotte not only embodies the beauty and the grace of the equestrian, but is also a wonderful ambassador for the sport. I am delighted to be able to celebrate Gucci's icons of heritage with someone who is so connected to the history and essence of this house. Charlotte brings the spirit of Gucci to life so elegantly, Gucci creative director Frida Giannini said about Casiraghi.

The 25-year-old granddaughter of Grace Kelly has had a close relationship with the fashion house for some time now. In the past, the young Monaco royal has worn riding outfits designed exclusively for her by the fashion house.

The campaign is one of those rare times when a royal has collaborated with a fashion house to front a product or collection.

Princess Charlotte is regarded as a fashion icon and has received intensive coverage by the media through the years.
