and Kate Middleton
's royal wedding
this month won't just be one for the history books. It could be one for the record books, too.
So which official Guinness World Records do the royal couple have a chance of breaking?
The most obvious record is the size of the TV audience for a wedding, which was set in 1981 by William's parents, Charles and Diana.
But that's just the beginning: below, check out William and Kate's chances at beating this, and several other wedding-related Guinness benchmarks.
Biggest TV audience for a wedding
Some 750 million people in 74 countries tuned in for Prince Charles and Lady Diana Spencer's nuptials on July 29, 1981. Some observers believe William and Kate's wedding could draw 1 billion viewers; others think it might not even match the 750 million.
Most expensive slice of wedding cake
A piece of the Duke and Duchess of Windsor's 1937 wedding cake sold at Sotheby's in 1998 for $29,900. William and Kate have settled on a multi-tiered, traditional fruitcake
baked by Fiona Cairns. Sixty years from now, the leftovers should also be worth a bundle.
Most searched-for celebrity wedding
Khloé Kardashian and Lamar Odom's 2009 wedding
holds this Internet distinction. They're a power couple, to be sure – but not with the worldwide appeal of the prince and future princess.
Longest wedding dress train
Created by Lichel van den Ende in 2009, it measured more than 8,164 ft. – about a mile and a half. And though Kate's dress is expected to live up to Westminster Abbey's grand aisle, she won't be rolling out a record-breaker here. For royal reference: Diana's wedding train in 1981 was 25 ft. long. Sarah Ferguson's train measured 17 ft. long when she married Prince Andrew in 1986.
Largest wedding bouquet
The bouquet at a Canadian wedding in 2003 was over 197 ft. long and included some 1,500 flowers. William and Kate likely won't have anything quite that big, but they do plan to leave their floral arrangements at Westminster Abbey for the public to enjoy in the days after the ceremony.
Most crystals on a wedding dress
A Romanian woman sported a snazzy 43,008 crystals on her wedding dress in 2010. Something tells us that Kate will make her formal entrance into the royal family with significantly less bling – on her dress, anyway. Keep an eye out for a fabulous tiara!
