NEW VIDEO: A Tour of Prince William & Kate's Royal Wedding Church

Prince William and his fiancée Kate Middleton will walk down the aisle on April 29 2011, and we have a special tour of what exactly will happen at Westminster Abbey on the royal day!

From Kate's grand entrance to where she will leave her bouquet, the Very Reverend Dr. John Hall walks ET through the rituals and the events of the special day.

"Well, the first thing to say is that we're delighted they're getting married. Congratulations on their engagement. And, of course, we're very happy indeed that they're coming to Westminster Abbey," says the reverend.

On the big day, chairs will be facing inwards so everyone will be able to see the royal arrivals. After a long walk in front of thousands, the bride will be given away by her father on the landing in front of the great altar.

"It's quite intimate as a place," says the reverend. "When the couple is standing at the altar you have a good view of them … and it seems quite close."

One expected ritual will actually not take place during the wedding, and that's when the groom kisses the bride.

"They won't kiss during the ceremony," explains the reverend. "We don't do that in the Church of England. That's sort a Hollywood thing about, 'Now you may now kiss the bride' – it doesn't happen here."

Even with the formal British decorum, people can expect a moving ceremony.

"It's going go be a memorable, important occasion," says the reverend.
