WHITFIELD: Great Britain is preparing for a real-world fairy tale wedding one week from today. Prince Harry and American actress, Meghan Markle, are set to walk down the aisle next Saturday. And we just learned the head of the Episcopal Church, a bishop from Chicago, will give the address. CNN's Max Foster takes us behind the scenes at St. George's Chapel where the couple will be wed.</s>MAX FOSTER, CNN LONDON CORRESPONDENT (voice-over): Windsor Castle, home to kings and queens for nearly a thousand years, and within its grounds, St. George's Chapel where many members of the family have been baptized, married and, yes, buried. When Meghan Markle is driven into these hallowed grounds, packed with special guests, she'll mark a new chapter in this most famous of family histories. (on camera): The car will come into what will be a quite eerily quiet cloister. It will stop here. The first thing that will confront the bride is some 20 steps leading up to the chapel.</s>FOSTER (voice-over): And with the words, "I will," an American celebrity becomes British royalty.</s>FOSTER: Max Foster, CNN, Windsor, England.</s>WHITFIELD: And tonight, CNN's Alisyn Camerota shares the untold stories of Prince Harry and Meghan Markle.
