The royal trio stepped out alongside Daniel Craig and the film's stars for the London premiere
The name is Kate, Princess Kate!
Kate looked regal in a bespoke full length grey blue silk chiffon gown with a crystal embellished belt accessorised with the silver Casa clutch by Jenny Packham.
And in true Bond style, Prince William and Prince Harry both wore black tie for the glittery red carpet, where stars Daniel Craig, Monica Belucci and Naomie Harris arrived earlier to the delight of screaming fans.
The royal movie night is Kate’s second Bond moment in a week – on October 21, she wowed in a plum lace Dolce & Gabbana gown during an event where Bond’s Aston Martin DB10 was on display.
A few hours before the Monday premiere, Kate and William took part in another film-based event, the Charities Forum hosted by BAFTA, in which the royal parents had some fun with kids and helped promote the causes close to their hearts.
Spectre is the 24th installment of the James Bond franchise and sees Craig step into the role for the fourth – and possibly final – time.
Filmed in Mexico City, Rome, the Austrian Alps and London, the movie sees Bond take on a shadowy crime syndicate led by Christoph Waltz.
French actress Léa Seydoux and Italian beauty Belucci also feature, alongside Guardians of the Galaxy star Dave Bautista.
