Kate Middleton made her demands clear to her then-boyfriend Prince William.

Kate Middleton once slapped a bold condition on her attending the royal family's Christmas celebrations – telling Prince William she would only join the Sandringham festivities once she had an engagement ring.
RadarOnline.com can reveal before her engagement, the 43-year-old made it clear to her then-boyfriend that she would not attend the Queen's traditional Christmas lunch at Sandringham without a formal commitment.
Kate Middleton Needed an Engagement Ring
Middleton set a clear boundary before attending the Sandringham Christmas celebrations.
Royal historian Robert Lacey says in his book Battle of Brothers: "By 2006, the couple had been dating seriously for the best part of five years. Yet when William invited Kate to join him that year at Sandringham for the royal family's traditional Christmas lunch, she refused.
"It was the first time the Queen had extended such an invitation to an unregistered 'girlfriend,' but Kate had her own take on that break with tradition: she would go to Sandringham on Christmas Day only when she was engaged and had a ring to prove it."
A palace source told us Middleton's decision reflected both her confidence and a desire to be respected as a serious partner.
"Kate was intent on establishing her own boundaries," a palace insider explained. "She wanted certainty and a formal commitment before stepping into such a prominent family environment, and she communicated that clearly to William."
At the time, she and William had been navigating the pressures of public attention, with the prince already in the line of succession and under constant scrutiny.
A Royal Christmas Details Revealed
Middleton is said to prioritiz respect and certainty over royal tradition.
Another insider added: "It wasn't an act of defiance – it was about setting clear boundaries and making sure she was recognized as more than just a girlfriend within the very traditional royal family setting."
The pair eventually became engaged in November 2010, before marrying at Westminster Abbey on April 29, 2011. They have since welcomed three children: Prince George, 12, Princess Charlotte, 10, and Prince Louis, 7.
This year, the family of five will join King Charles, 77, and Queen Camilla, 78, at Sandringham for the traditional Christmas festivities.
The gathering in Norfolk will also include Zara and Mike Tindall and their three children – Mia, Lena, and Lucas – as well as Princess Anne, with her husband Sir Timothy Laurence.
Queen Camilla's children will not attend this year. A source close to the couple said Kate and William aim to balance royal obligations with family priorities.
Middleton is said to have told her husband she wanted a formal commitment first.
The source explained: "Their focus is on the children. Christmas is about them and making memories in a way that keeps them out of the public eye."
Recently, William and Middleton shared their annual Christmas card portrait, which delighted fans across social media.
The photo, taken in Norfolk by photographer Josh Shinner, shows the family sitting on grass surrounded by daffodils. "Wishing everyone a very Happy Christmas," the couple captioned the image.
Fans flooded the post with messages of admiration. "Beautiful family! Merry Christmas to you all from Sunny Florida, USA," one user wrote.
Another added, "May your smiles reflect the happiness in your hearts. Merry Christmas!"
A royal insider said the family card, like the Sandringham festivities, reflects Middleton's careful approach to blending tradition with modern family life.

Middleton defined her role long before becoming Princess of Wales.
The source said: "Kate has always been deliberate about her role and her family's image. She's firm and thoughtful, knowing when to take a stand–whether for an engagement ring or for her family's Christmas. Her 2006 ultimatum will be for William to double down on bringing stability to their family life."
