The wedding of Prince William and Catherine Middleton.

William's private life became the subject of tabloid speculation and gossip, especially around his relationship with Kate Middleton, who had been one of William's university flatmates and whom William began dating in 2003. Middleton attended the Prince's passing-out parade at Sandhurst, marking the first high-profile event that she attended as William's guest. The relationship between Prince William and Middleton was followed so closely that bookmakers took bets on the possibility of a Royal Wedding and the retail chain Woolworths produced memorabilia bearing the likenesses of the two.[56] Media attention became so intense that William had to make a specific request to the paparazzi that they keep their distance from Middleton and him. In March 2007, Middleton complained of media harassment by the Daily Mirror.[56] It was reported in April 2007 that the couple had split,[56][57] though in June, Middleton attended a party at Lulworth Army Barracks as the guest of Prince William,[58] in July she attended the Concert for Diana, which had been organised by Princes William and Harry.[59] in August, she accompanied William on holiday in the island of Des Roches in the Seychelles, and in October she joined Prince Charles and Prince Harry for a shooting party at Balmoral. In June 2008, along with the Royal Family, Middleton attended William's investiture into the Order of the Garter.
On 19 October 2010, on a trip to Kenya, the 28-year-old prince proposed to Middleton at Lewa game reserve, a favourite spot for Prince William.

Finally, they are going to marry on 2011.
