Prince Charles\' wife Camilla said Wednesday she watched her step-son Prince William\'s wedding again on the television to catch up on the bits she missed. The Duchess of Cornwall, who was visiting the Northern General Hospital in Sheffield, northern England, told one patient that the wedding was \"fantastic\". \"I had to go and watch it back on TV later to see what I\'d missed,\" she said. Camilla had a front-row seat in Westminster Abbey on Friday and her grand-daughter Eliza Lopes was one of the bridesmaids. Charles picked up the three-year-old on the Buckingham Palace balcony so she could see the crowds. \"It was a bit of a worry whether she was going to get up the aisle or not, but thank goodness she made it,\" the duchess said. William took his new bride Catherine for a spin in an Aston Martin car after the wedding, in a light-hearted moment that suprised the crowds outside Buckingham Palace. The convertible Volante DB6 MKII in Seychelles blue belongs to Charles, who has owned it since 1969. The environmentally-aware heir to the throne had it converted in 2008 to run on E85 bioethanol, made from English wine wastage. Asked if Charles was giving it to William, Camilla replied: \"No. He\'s got the car back now. He won\'t let go of that.\" Charles is on a two-day official trip to Washington, where he was due to meet President Barack Obama at the White House.
