Prince William and girlfriend Kate Middleton

Prince William and girlfriend Kate Middleton have the engagement news that the world has been waiting for and will marry next spring or summer in London. The announcement Tuesday by royal officials ends an on-again, off-again romance that began after the two met more than eight years ago as students at the University of St. Andrews in Scotland. Prince Charles' Clarence House office said the heir to the British throne is "delighted to announce the engagement of Prince William to Miss Catherine Middleton." It said they got engaged last month during a vacation in Kenya.
