Kate Middleton received warm greetings from senior members of the British Royal Family on her birthday. On Sunday, Queen Elizabeth II, Prince Charles, and Camilla, Duchess of Cornwall, shared their respective tributes to Prince William's wife on social media platforms.

With the Sussex Royals no longer part of the Royal Firm, many were wondering whether they greeted their sister-in-law, as well. While no official word has come to light, Us Weekly recently learned that Prince Harry and Meghan Markle did a video call with the Duchess of Cambridge.

As reported, the former senior working royals ensured to send their regards to the future Queen Consort. Christopher Andersen exclusively revealed to the publication that the Duke and Duchess of Sussex "wished her a happy birthday," adding that the engagement was "very private."

The royal expert noted that the Sussex Royals did not share the greetings in public as opposed to what they did in 2020. He recalled that the couple displayed their "affection" for Kate Middleton during her 38th birthday on their official social media accounts.

This time around, though, "everything was kept private." Andersen did not dwell on the details as to why, but he asserted that several things have already changed between the Sussex Royals and Cambridge Royals.

As for the celebration, it is said that the Duchess of Cambridge hosted a "small family affair" at Anmer Hall. She welcomed family and friends in their estate, adding that she has an "interesting tradition" of baking her own cake.

Overall, the party was "low-key" as previous reports had predicted. Marie Claire, also, pointed out that it is "all about family" for Kate Middleton.

This came after a royal expert shared that the Duchess of Cambridge's celebration would look "nothing like" Meghan Markle's. Duncan Larcombe recalled that the latter took the opportunity to launch her charity initiative during her 40th birthday a few months ago.

He continued that the future Queen Consort is not a person who makes a "big deal" out of birthdays.

Earlier last week, though, Kate Middleton commemorated her special day, according to People. Kensington Palace published three new portraits of the British Royal in celebration of her 40th year.

Alongside the warm birthday greetings, the Duchess of Cambridge, also, received praises and compliments from the public because of the portraits. The publication even described the photos, which photographer Paolo Roversi took last November, as "worthy of a future Queen."
