About an hour after they arrived back at Buckingham Palace, Prince William and HRH Duchess of Cambridge Catherine Middleton stepped out onto the balcony and waved to the crowd with their families in tow. As expected, the two kissed for a millisecond and the crowd erupted in applause and cheers. The royal couple laughed at the overwhelming reaction, which prompted them to kiss once more. Once the Queen seemingly had enough of the scene, the royals gave their final waves and walked back inside. Before disappearing inside, the gracious and poised Kate looked back with a smile at all of the people who waited excitedly for her big day.
