Charlotte Casiraghi, the Monaco royal and noted equestrian, is back in the saddle for Gucci, repping the brand’s famous “horsebit” accessories in her fourth photo shoot as a model.

The granddaughter of late Grace Kelly and daughter of Princess Caroline, debuted in her first photo shoot for Gucci in March. The princess had her fashion coming out party last year in Vogue Paris.

In the latest stills, photographers Inez Van Lamsweerde & Vinoodh Matadin, shot Casiraghi in black and white. She lounges on a divan in casual dress, wearing a white shirt, slacks and loafers.

In a second photo she’s seated on the floor, lying against the sofa, her head propped up by her hand. Her hair is pulled back and she’s wearing jeans, a long-sleeve shirt and casual white loafers.

Gucci Founder Guccio Gucci first used the iconic metal horsebit on the brand’s saddle-stitched handbags.

“It is a real pleasure to collaborate with Frida Giannini and Gucci to celebrate one of the House’s most elegant symbols: the horsebit,” said Casiraghi in a statement. “The atmosphere on the set was very natural and intimate which made that moment very special.”

The “Forever Now” campaign was unveiled in March, lensed by Peter Lindbergh.

Charlotte is fourth in line to the throne of Monaco. Her father, Italian industrialist Stefano Casiraghi, was killed in a boating accident
