The Duke and Duchess of Cambridge arrived to cheers as they walked the BAFTAs red carpet at the Royal Albert Hall in London.
Kate, 37, channelled Hollywood glamour in a white one-shoulder gown with tulle flowers embroidered on one shoulder.
She teamed it with glittery heels and and had her brunette locks styled into an intricate updo.
Adding a sweet, family touch, Kate accessorised with a pair of Princess Diana’s diamond and pearl earrings.
The Duke has been President of the Academy since February 2010 and the royals are regular guests of the A-list event.
Last year, Kate chose a dark green empire-line gown by designer favourite Jenny Packham with emerald jewellery, when she was pregnant with Prince Louis.
Meanwhile in 2017, she wowed in a floral-printed off-the-shoulder dress by Alexander McQueen, teamed with statement earrings.
Earlier today, Kensington Palace revealed further plans for the Duchess of Cambridge, architects Andrée Davies and Adam White, and the Royal Horticultural Society’s Chelsea Flower Show garden design.
The ‘Back to Nature Garden’ will have a natural woodland feel and contain a treehouse, a waterfall and stream, a rustic den, a campfire and stepping stones.
