We know her as Kate Middleton, but the wife of Prince William of Wales and the future princess of England is officially known as Her Royal Highness The Duchess of Cambridge.
In the only ceremony of the decade that could honestly be described as a "fairy-tale wedding," William married Kate on April 29, 2011 at Westminster Abbey in London, England. Some estimates put the TV audience for their nuptials at 2 billion. That's 4 billion eyes waiting to glimpse Kate's dress, and the gown did not disappoint.
Known for her keen sense of style, Kate's elegant and modern Sarah Burton gown impressed even the most snooty fashion critics and inspired knockoffs and replicas instantly. Alexander McQueen's Burton also designed the cowl-neck bridesmaid dress worn by Kate's sister, Pippa, which became just as sought-after.
Even Kate's casuals make headlines; her every fashion choice consistently flies off store shelves and entire websites and fashion columns are dedicated to dissecting her style. When she announced her pregnancy in December 2012, fashion sites everywhere began to salivate about her choices for maternity-wear.
Before becoming the world's most regal fashionista, Middleton was just another student at the University of Saint Andrews, Fife, where she and Prince William met.
William and Kate were roommates in a four-bedroom apartment with two other coeds in 2002, which created a lot of buzz about the possible couple sharing living quarters. They didn't go public with their relationship, however, until 2004 while on a ski trip in Klosters.
As time wore on, British tabloids constantly speculated about when the prince would pop the question. When it seemed as though he was dragging his royal feet, the tabloids gave Kate the nickname "Waity Katie."
Instead of an engagement, William and Kate made news in 2007 when they decided to go their separate ways. Fortunately, they reunited shortly after the split, and in November 2010, William and Kate announced their engagement.
Kate is not only following the late Princess Diana's footsteps as a fashion icon, she seems to have Diana's passion for philanthropy as well.
Kate and William raised over $1 million in a single day for UNICEF and the couple raised over $17 million at a dinner they attended for Ark in 2011. Kate is also the patron of four charity organizations and as of July 2012, it was reported that she was considering doubling that amount.
The duchess made news when it was announced that she and her husband were expecting their first child. Despite being hospitalized in late 2012 for hyperemesis gravidarum, a rare and dangerous form of morning sickness, Kate even continued her charitable giving in the early days of her pregnancy, making a well-publicized donation of baby items to a children's hospice.
She and Prince William welcomed their first child, a boy weighing 8 lbs 6 oz., on July 22, 2013.
