Six words that Prince William won't be hearing on his wedding day are "You may now kiss the bride."
Church of England protocol prohibits him from kissing Kate Middleton during their marriage service at Westminster Abbey.
"There will be no kiss during the wedding ceremony," explained the Very Reverend Dr. John Hall, the dean of Westminster. "We don't do that in the Church of England. That's sort of a Hollywood thing: ' You may now kiss the bride.' It doesn't happen here."
Barring a few secret smooches on the way to Buckingham Palace following the service, the newlyweds will have their first kiss at 1:25pm on the palace's balcony for the public to see (and photograph).
There's reports that Will and Kate have been practicing their kiss so that photographers will capture the perfect angle.
Here are five other royal wedding burning questions answered:
Question: Where will Kate toss her bridal bouquet?
Answer: There will be no tossing of the bridal bouquet. Per tradition, Kate will be placing the flowers on the grave of an unnamed soldier who fought in WWI. Sorry, bridesmaids.
Question: Who is Kate's maid of honor?
Answer: Pippa Middleton, Kate's younger sister, will serve as her maid of honor. In TMZ's recent "Who'd You Rather," Pippa lost to her big sister by a whopping majority. Too bad she won't get a chance to catch the bouquet (see above).
Question: Who is Prince Harry's date?
Answer: Chelsy Davy, Harry's on-again, off-again girlfriend, will be his companion for the evening. The beautiful blond will reportedly be wearing dresses by Alberta Ferretti, who offered to dress her for free. She ain't a princess-to-be yet!
Question: Are President and Michelle Obama invited to the royal wedding?
Answer: According to the official guest list, the President and First Lady are not invited to the royal wedding (they'll spend the day watching a shuttle launch in Florida). David and Victoria Beckham are. So is Mr. Bean. Diss!
Question: What will Kate's title be after wedding William?
Answer: Officially, she will be known as "Her Royal Highness Princess William of Wales" (Princess Catherine is technically incorrect since she was not born a princess). If you ask us she's too pretty to be called Princess William.
