Catherine Middleton

William's private life became a subject of tabloid speculation, especially around his relationship with Catherine Middleton, one of William's university flatmates whom William began dating in 2003. Middleton attended William's passing-out parade at Sandhurst, which was the first high-profile event that she attended as his guest. Their relationship was followed so closely that bookmakers took bets on the possibility of marriage and the retail chain Woolworths produced memorabilia bearing the likenesses of the couple. Media attention became so intense that William formally asked the press to keep their distance from Middleton.
