Kate gets into the Olympics spirit

The Duchess of Cambridge showed her support for London 2012 by wearing an Olympic-themed necklace.

With excitement growing ahead of the start of the Games, Kate stepped out for a viewing of Team GB and ParalympicsGB athlete portraits in the jewellery which featured five rings - the symbol of the global sporting event.

Her large gold-coloured chain had a ring on each shoulder, another further down on each side and a large hoop at the bottom.

She completed her Olympic look with a blue crepe dress by Stella McCartney - who has designed a range of clothing the athletes will wear when competing, training and relaxing.

London's National Portrait Gallery was the venue for the exhibition, Road To 2012: Aiming High, the third and final instalment of a three-year project that has showcased world-class Olympic and Paralympic athletes and those working behind the scenes.

Last year the Changing Pace exhibition was staged and in 2010 Setting Out was the name of the inaugural event.

Among those photographed for the exhibition are the men's rowing eight, taekwondo fighter Jade Jones, London Mayor Boris Johnson and Turner Prize-winning artist Anish Kapoor, who co-created the ArcelorMittal Orbit sculptor at the Olympic Park.

The portraits have been taken by photographers Jonathan Anderson & Edwin Low, Nadav Kander and Jillian Edelstein.

The Duchess has a close connection with the National Portrait Gallery as she is its patron and has a formal role with the Olympics as an Ambassador for Team GB and ParalympicsGB.

A St James's Palace spokesman said of the necklace: "It's a personal piece which she's had for some time. It's not an official Olympic item but it's appropriate to wear it."
