The queen's subjects are going from afternoon tea to hard public partying.
The royal wedding of Prince William and Kate Middleton is proving to loosen up these normally reserved folks. With most of the country's residents off on Friday for what has been declared a national holiday, they need to find somewhere to watch this history unfold.
So they're taking to the streets like animals! OK, we know they'll be on their best behavior, but they still plan on drinking their faces off and ripping it up like rock stars.
See where they'll throw back some pints for their future king and queen...
First, there's the King's Road area, where Kate loves to shop, which is planning on hosting a number of outdoor festivals. Anything and everything British they can think of will be making an appearance: horse-drawn carriages, vintage British cars, Pimm's mixed drinks and royal couple-themed games and stands set up all over the area.
"There will be crowds here in Duke of York Square," said one employee named David at the agnes b. shop in the square. "This area is not as exposed to the public. It is hidden, so that's the advantage here. It'll be all locals gathered to watch."
There will be huge flat-screen TVs set up in the area outside the store, along with seating, food and champagne stands for everyone to get tipsy.
"We want to celebrate them. I think it's good, and Kate is a good choice," David told E! News "There's no bad press on her."
The party in the square, which begins at 9:30 a.m., will even feature an early afternoon fashion show in honor of the new couple and a stand where partiers can record fun, drunken messages to the couple.
And if all that doesn't wipe out the hard-partying Brits, there's another day-long bash starting the very next morning in the exact same spot. That's a double doozy.
Even London's famed, upscale Bluebird Cafe will turn into Brits Gone Wild on the morning of the wedding with a bash of its own that will spill into the street.
"We're having a party out in the courtyard if it doesn't rain," restaurant manager Tiffany Goodall told E! News. "There will be 140 people out there and a screening at the bar upstairs."
Goodall says by Friday the normally sedate eatery will turn rowdy and erect three 65-inch TVs outside near the road, along with four inside—two 50-inch and two 42-inch—for diners to watch.
"We're having an all-day barbeque, along with traditional British fare like smoked salmon, scrambled eggs and a lot of Pimm's," she said.
The restaurant will also hang Union Jack flags throughout and have a special "royal menu" for later that night featuring the country's traditional coronation fare: chicken and lobster. They've even created a Royal Rose cocktail and are serving pink champagne.
All over Chelsea and over in London's East End, chalkboards line the sidewalks promoting royal-themed parties and drinks. Tiny plastic flags stamped with the couple's face can be seen hanging at nearly every newsstand and in store windows.
Following all that daytime drinking will, of course, be the afterparties. At the George Tavern, smack center in the city's East End, will be a crazy, late-night bash called "Love to Love, the Royal Wedding Reception," which will have a wedding cover band and two DJs.
In the South End of the city, a new pub set to open Friday is even advertising its own take on a royal-themed bash. At the Royal Vauxhall Tavern, if you show up wearing a wedding dress, consider the five-pound entry fee waived.
For those not attending "official" street shindigs or themed parties, many will hold what Londoners are calling "street meets," which is like a good-ol' American block party, where neighbors will come together informally to talk royals and share food.
"We all want to feel patriotic," Bluebird manager Goodall says of all the festivities. "We want everyone to muck about and have fun."
Done and done.
