ET's Chris Jacobs is front and center with the official Buckingham Palace horse brigade, which will play a crucial role in the Royal Wedding of Prince William and Kate Middleton.
Chris and his ET crew get an up-close look at last-minute rehearsals for the horses used to carry the Royal Family carriages as well soldiers guarding all royal grounds. The magnificent animals are kept on the premises at Royal Mews, which has existed at Buckingham Palace since 1761.
The horses are mainly Cleveland Bays, the only British breed of carriage horse, and Windsor Greys, which by tradition always draw the Queen's carriage. For many of the horses it will be their first major royal event so they will be exercised early in an attempt to keep them calm, and then groomed like never before.
Watch the video to catch a glimpse of the precision maneuvers being practiced in advance of Friday's main event!
