The most anticipated wedding of the year has come and gone. Prince William and Kate Middleton are officially a married couple. In a beautiful ceremony in Westminster Abbey among world leaders and close friends, the couple exchanged vows. Kate Middleton's dress was the Royal Wedding's best kept secret. As has been speculated before, Middleton's dress was by the head designer of Alexander McQueen, Sarah Burton. Burton took over as creative director of Alexander McQueen after his tragic suicide. Burton has worked with McQueen for 14 years and has previously designed dresses for Michelle Obama, Cate Blanchett, Lady Gaga, Gwyneth Paltrow and Sara Buys. Kate Middleton also chose to wear the Cartier halo tiara, which was made in 1936 and given to the Queen as an 18th birthday present. It is unclear whether the tiara was borrowed or if the Queen gave it to Middleton as a gift.After the ceremony, the couple made their way to Buckingham Palace where they shared the much-anticipated kiss. Following a ceremony hosted by the Queen in Buckingham Palace, the couple drove off in an Aston Martin with Prince William in the driver's seat. This was a nice, modern touch to a fairytale wedding. While at Buckingham Palace, William and Kate posed for official photos with their families.
