But now the the Duke and Duchess of Cambridge, as the couple is officially known, are advertising for household servants to help with the realities of day-to-day life, from housekeeping to dressing.
The royal call for help comes as the couple settles in after marriage and prepares to move into their new London apartment at Kensington Palace, William's childhood home.
After a delayed honeymoon in Seychelles following their fairy tale wedding at London's Westminster Abbey April 29, William and Kate initially made good on their word to live a more modest, royal life.
The young royals, who lovingly call themselves Mr. and Mrs. Wales, chose a modest cottage in Wales over Buckingham Palace, and resisted taking on butlers and servants.
William returned to work as a search-and-rescue pilot in Anglesey, while Kate was seen grocery shopping for the couple herself.
Their primary residence will remain a small house in Anglesey, an island off the coast of northwest Wales where William, 28, serves as a Royal Air Force helicopter rescue pilot.
But Kensington Palace will now be their London home, to accommodate the couple for weekend and official visits.
The couple had previously been staying with William's brother, Prince Harry, at St. James Palace during their London stays.
The move to Kensington means the couple will now have a place of their own, and all the demands that come with being a royal "homeowner."
"Six months time someone will be boiling their eggs for them and putting toothpaste on their toothbrushes. "
The new hires, palace officials say, will be based in London and will not be required to travel when the couple returns to their home in Anglesey.
Royal Life vs. Real-Life
William grew up in Kensington Palace, living there as a child while his parents, Prince Charles and the late Princess Diana, were married, and then staying on with his mother after their divorce.
Princess Diana used the palace as her primary residence until her death in 1997.
"They won't live in the whole place," Larcombe told "GMA." "It's an enormous, sprawling building."
William and Kate will share space with other royals who also live in the palace, which is broken up into a number of apartments.
The late Princess Margaret, the queen's younger sister, lived there for many years, and it was also the birthplace of Queen Victoria.
But it is Princess Margaret's apartment, where she is said to have hosted the Beatles and others when she lived there, that will become William and Kate's new home.
"They will be moving into a small apartment temporarily while, we believe, while Princess Margaret, the Queen's late sister, while her old apartment is completely rewired, renovated, and security upped," said Larcombe.
The couple plans to complete their move before embarking on their first official overseas trip to Canada and the United States later this month.
William and Kate will embarkJune 30 on a nine-day, eight-city tour that will take them from Ottawa and Montreal through the Northwest Territories of Canada before making their way down to Los Angeles for a grand finale.
The overseas trip will mark their first as a married couple, and an opportunity for the newlyweds to showcase the new breed of monarchs that some are calling the "modern royals": going to college, having careers and marrying for love.
It will also be a chance for royal gazers to watch how the young couple will put their own stamp on centuries of royal tradition, and how well Middleton's "dresser" is doing.
Palace watchers expect her wardrobe for the U.S. and Canada tour to include three dress changes per day, amounting to 40 outfits in all for the young bride.
While Diana famously drew from designers and fancy gowns, Middleton, 29, has gone for more affordable and accessible wear, including a Burberry trench coat that sold out as quickly as photographs of her in it surfaced.
Palace officials stress that 'dresser' does not mean 'stylist,' though, and that Middleton will still choose her own clothes.
She will also appoint her own stylist. Middleton will reportedly personally interview the applicants, and hopes to appoint someone before she and William fly to Canada on June 30.
During their visit, which is being paid for by the Canadian government, the newlyweds will tour the Canadian airfield where Middleton's late grandfather, Peter Middleton, was based as an RAF pilot during the Second World War.
They will also make time for more lighthearted moments when they visit the country's smallest province, Prince Edward Island, the location featured in Middleton's favorite childhood book, "Anne of Green Gables," and open the Calgary Stampede, the world's largest rodeo.
Once in the United States, the couple is expected to attend a series of charity events and meetings in the Los Angeles area.
Palace officials say the couple will take scheduled flights back from Los Angeles, not the private jets long favored by royals such as William's father, Charles. And the Canadian government will pay the cost of flying William and Kate to Canada on a jet.
