Duchess of Cambridge Catherine or Kate Middleton and Prince William have officially began their duties as a royal couple (and we don't mean sorting out grandchildren for the Queen); the royal couple stepped out in London to attend a fancy fundraiser at the 10th annual Absolute Return for Kids (ARK).

Top 10 details about Kate and William's wedding

According to People.com, Kate arrived in a blue sleek Jaguar and "in a floor-length blush organza Jenny Packham gown", amidst the flashing cameras. Prince William, 28, gave his first speech since his wedding and quoted as saying: "Harry and I find ourselves in a position to be able to help. I really believe that individuals can make a serious difference - whether it's through wealth, through position, or some other advantage," he said. "Catherine and I hope to use our philanthropy as a long-term catalyst for meaningful change."

On a separate occasion, the royal couple have also been spotted attending church service to mark the 90th birthday of Queen Elizabeth II's husband Prince Philip at the Royal Chapel, Windsor Castle, west of London, Sunday June 12, 2011. Philip, also known as the Duke of Edinburgh, married the queen in 1947. He is the son of the late Prince Andrew of Greece and a great-great-grandson of Britain's Queen Victoria, giving him deep royal roots. He turned 90 on Friday. [credit AP]
