London:
Prince William and Kate Middleton look relaxed, poised and very much in love in official photos released to mark their engagement.
One of the two images shows the couple, dressed in casuals, smiling in each others' arms. Kate's left hand is on William's chest and clearly visible is the engagement ring -- an oval sapphire surrounded by diamonds that belonged to the late Princess Diana.
Both wear jeans, with Middleton sporting a blouse from retailer Whistles and William wearing a brown sweater over a white shirt from traditional tailors Turnbull and Asser.
The other, more formal photo, depicts them standing together in a state room at St. James's Palace on a red carpet -- in front of oil paintings of ancestors. William wears a gray suit and blue tie over a white shirt and Kate a smart white dress from Reiss.
The pictures, released Sunday by the Prince's office, were taken by fashion photographer Testino, a royal family favorite who captured some of the most iconic images of William's late mother, Princess Diana.
Testino said the couple appeared "in their prime and brimming with happiness" when he photographed them on Nov 25.
William, who is second in line to the British throne, has inherited his mother's poise.
In both pictures he and Middleton appear entirely comfortable with the camera and each other.
William and Middleton, both 28, announced last month that they will marry on April 29 at Westminster Abbey in London.
