Many media experts believe the nuptials will break the current world record for the largest TV audience for a wedding, which was set July 29, 1981, during the marriage of William's father, Prince Charles, to Lady Diana Spencer.
That wedding was watched by an estimated 750 million people in 74 countries. Considering that the world population has jumped by more than 2 billion people since then -- from 4.5 billion to 6.7 billion, with a corresponding rise in TV viewership -- it's a safe bet that this royal wedding audience will leave Princess Di and Charles' wedding record in the dust.
The experts at Guinness World Records predict that the royal nuptials will be the most-searched-for celebrity wedding, topping the current record holder: the Sept. 27, 2009, ceremony between reality TV star Khloe Kardashian and Los Angeles Lakers star Lamar Odom.
Other records that could conceivably be conquered by Kate and William include:
- The longest wedding veil. The current record is more than 11,017 feet long and was worn by Sandra Mechleb at her wedding to Chady Abi Younis in Arnaoon, Lebanon, on Oct. 18, 2009.
- The most crystals on a wedding dress is 43,008 and was achieved by Cosmina Englizian and presented at an event organized by E-Mariage in Romania, on March 24, 2010.
- The largest wedding cake weighed 15,032 pounds, could feed 59,000 people and was made by chefs at the Mohegan Sun Hotel and Casino in Uncasville, Conn., and displayed at its New England bridal showcase on Feb. 8, 2004. No word on how much dough it cost.
- The longest wedding dress train measured more than 8,164 feet and was created by Lichel van den Ende. It was presented and measured in Zoetermeer, Netherlands, on Dec. 22, 2009, and the designer still has the record sewn up.
For instance, there's the one for "Largest Underwater Wedding," which was achieved by 261 divers who took part at the marriage ceremony between Francesca Colombi and Giampiero Giannoccaro at the Morcone beach, Capoliveri, Elba Island, Italy, on June 12, 2010.
Meanwhile, the record for the "Largest Dog 'Wedding' Ceremony" was achieved by 178 dog pairs who sealed their marriage with a bark on the notes of the wedding march at the "Bow Wow Vows event" organized by the Aspen Grove Lifestyle Center in Littleton, Colo., on May 19, 2007.
Considering the stress associated with planning a royal wedding, it is doubtful that Kate and William will want to go through the hassles of breaking the record for vow renewals set by Lauren Lubeck Blair and David E. Hough Blair, who have pledged to have and to hold each other till death to they part a whopping 99 times.
The couple have slowed down a little bit in recent months and haven't rehitched since they last did it on Oct. 11, 2010 at Logan's Roadhouse in Gallatin, Tenn.
