Kate Middleton teamed up with her husband Prince William's grandmother, Queen Elizabeth, this morning in London to tour the Summer exhibit at Buckingham Palace. The show has Kate Middleton's wedding dress on display, in addition to other mementos from her and William's April 29 ceremony. The Queen and Kate also checked out a replica of their wedding cake, her actual shoes, and a video featuring the woman behind the iconic gown, Alexander McQueen's Sarah Burton. Queen Elizabeth didn't like the mannequin wearing Kate's dress, according to reports, calling the headless form "horrid" and "horrible." Today was the first of many days the Duchess of Cambridge and the Queen will spend together: Queen Elizabeth has invited William and Kate to spend time with her at the royal place in Balmoral, Scotland, in a few weeks.
