Kate Middleton and Prince William at Wedding on Anniversary

Prince William and Kate Middleton attended a friend's wedding at the St. Andrew's Church in Wingfield, England, on Saturday. Her childhood pal Hannah Gillingham tied the knot with Robert Carter. Kate's sister, a Project D-clad Pippa Middleton, was also along for the ceremony, as was Richard Branson's daughter Holly. Kate wore an Erdem dress that she also sported during her and William's tour of Canada last Summer, but this time, she accessorized with an Alexander McQueen belt. Her clutch was from UK designer Anya Hindmarch.

William and Kate marked their own wedding, which was one year ago yesterday, privately. Despite a busy last week that included numerous public events and a dressed-up outing to the premiere of African Cats, William and Kate spent their anniversary together, just the two of them, at their Wales residence. According to reports, Kate wanted to prepare a meal of fish cooked in parchment. The dish was symbolic since a first wedding anniversary is symbolized by paper. William is expected to resume his work with the Royal Air Force in Wales today.
