Kate Middleton will arrive by car and leave in a carriage when she ties the knot with Prince Williamat Westminster Abbey on April 29. Key details about the upcoming nuptials emerged Wednesday; Charles' representative broke weeks of silence with a statement announcing Archbishop of Canterbury Rowan Williams will marry the couple in an 11 AM ceremony.

The wedding of William and Middleton, his girlfriend for nearly eight years, is expected to draw a gigantic global audience via television and the Internet. According to PopEater's Rob Shuter, this will be the most expensive celebrity wedding of all time and likely cost the British taxpayers more than $20 million dollars.

Britons and visitors can try to catch a glimpse of the couple as they glide by in a horse-drawn carriage, when it travels through Parliament Square, Whitehall, Horse Guards Parade and the Mall, or they can gather near Buckingham Palace, where William and his bride are expected to emerge into public view briefly on the balcony.
