The pictures were taken in St. James' Palace in London on Nov. 25. The pair will be wed April 29, 2011 in what will be the biggest royal family nuptials since Prince William's father Prince Charles wed his late mother Diana in 1981.
One of the two pictures of William and Kate taken by Mario Testino shows the couple, dressed in jeans and casual tops, smiling in each others' arms. The other, more formal, depicts them standing together in a state room at St. James's Palace.
The photographer is a royal family favorite who captured some of the most iconic images of Prince William's late mother, Princess Diana.
Kate Middleton did her own makeup for the photos, as she did for her televised post-engagement interview.
