Prince William and Kate Middleton stunned onlookers when they walked the red carpet Wednesday for the film premiere of Disney's 'African Cats.'

Duchess Kate Middleton, 30 wowed in a light grey three-quarter sleeve sheath dress with jade and turquoise trim around the collar and cuffs by Welsh designer Matthew Williamson, reported AFP. The dress sported an on trend peplum skirt. Duchess Kate finished off the outfit with a black clutch and a pair of black pumps.

WhatKateWore reported the Welsh designer added the jewels and beading on the color to match the cuffs per the Duchess' request.

Prince William, 29 wore a dapper navy blue suit with a magenta tie and a crisp white shirt.

The red carpet premiere was the couple's first official engagement since William's return from a six month deployment to the Falklands Islands.

They were the guests of honor at the London screening of 'African Cats,' a film about how cheetahs and lions teach their cubs to survive in the wild. Sir Patrick Stewart narrates the film.

Money raised from the premiere will go to Tusk Trust, a British based conservation charity that protects Africa Wildlife. Tusk Trust is supported by the Princes' Charities Forum, an initiative stated by Prince William and his brother Prince Harry in 2006.

The couple will make two media appearances tomorrow, one at the Scott-Amundsen Centenary Race and the other at the launch of the First World War Galleries: Centenary Campaign at the Imperial War Museum. Prince William will make a speech at both events, reported the Daily Mirror.

Prince William and Kate will mark their first wedding anniversary on Sunday.

A Clarence House spokesperson said the couple will spend the day alone.

William is cooking for them,' a friend of the couple told Grazia. 'It's a joke between them that his culinary skills were what originally wooed Kate all those years ago. They'll probably watch a DVD and reflect on the past year. They really are old before their time, and it's not very glamorous, but they're very happy.
