Will Prince William and Kate break these Guinness World Records with their April 29 royal wedding?

With less than a month to go before Prince William and his bride-to-be, Kate Middleton, tie the knot at Westminster Abbey, the media is abuzz with speculation over every last detail of the highly-anticipated ceremony.

The folks at Guinness World Records are guessing that after the pair says, "I do," they'll have broken several of the current records in the wedding category. Which are they most likely to smash? Here are five categories where we think the British royals have a shot.

1. Largest TV audience. When Prince William's father, Prince Charles, married Lady Diana Spencer (Princess Di) in 1981, an estimated 750 million people in 74 different countries tuned in to watch the magic unfold. With the growth of the media—and the world's obsession with celebrity weddings—this is one record Kate and her royal fiancé are sure to shatter. Royal Wedding: Will Kate Middleton Always Live In Diana's Shadow?

2. Most searched-for. In the age of new media, with information readily available with a click on Google, fans are turning to search engines to deliver the most up-to-date information on all things celebrity-wedding related. To date, the wedding of Khloe Kardashian to Lamar Odom of the LA Lakers takes the most-searched-for crown. Khloe Kardashian's Wedding Details

3. Largest wedding cake. With an impressive number of attendees on the guest list, Prince William and Kate will need a sizable cake to feed the masses at their royal reception. To date, the Guinness World Record holder for largest wedding cake weighed in at a whopping 15,032 lbs, and there were no British royals dining on the massive dessert—it was made by the chefs at Mohegan Sun in Connecticut for a bridal showcase in 2004.

4. Most expensive slice of wedding cake. Although we doubt we'll find a portion of Kate's traditional wedding fruit cake or Prince William's chocolate cookie cake for sale on eBay following the ceremony, we're sure if we did, the cost per slice would be hefty. But would it beat the price tag attached to a piece of cake from the Duke and Duchess of Windsor's 1927 ceremony? It was sold for $29,900 at Sotheby's in New York in 1998.

5. Record-breaking fashion. Kate's dress is perhaps one of the best-kept secrets of the royal nuptials thus far, and though many have speculated on which designer she'll choose and what style she fancies, there's no telling yet whether she'll approach this outrageous wedding-dress records. The most blinged-out gown was garnished with just over 43,000 crystals in Romania in 2010. The longest veil was worn by Lebanese bride Sandra Mechleb in 2009 and stretched over 11,000 feet long. And while Princess Di's train was impressively long, the record belongs to an 8,164 foot long train in the Netherlands. Get Married In Princess Di’s Dress
