The Royal Family’s official social media accounts, along with William and Kate’s Instagram and X accounts, posted birthday wishes for the Duke of Sussex.

Prince Harry has received some unexpected royal birthday wishes.

The Duke of Sussex turned 40 on Sunday, Sept. 15, and his milestone birthday was celebrated by both his father, King Charles, 75, and his brother Prince William, 42, in posts on social media, marking the first time the royal family has publicly acknowledged Harry’s birthday since 2021.

On the official Royal Family social media accounts, which are run by King Charles’ office at Buckingham Palace, a post celebrated Harry’s milestone birthday with a simple message.

”Wishing The Duke of Sussex a very happy 40th birthday today!,” the caption of the post read, alongside a photograph of the Duke smiling.

“Wishing a Happy 40th Birthday to the Duke of Sussex,” the caption above the photo read.

In July, sources told PEOPLE that Harry’s calls and letters to King Charles, go unanswered, and his attempts to connect with Prince William — through texts, calls, and messages — were similarly ignored.

However, while the royal insider noted that the rift with Prince William was “very bad,” they added that it was not “irreparable.”

The brothers last presented a united front with their wives, Kate Middleton and Meghan Markle,  after Queen Elizabeth’s death in September 2022, when they met mourners outside Windsor Castle

Amid the estrangement, Harry remains concerned for the safety of his wife and children.

A source close to the situation said, “Harry is determined to protect his own family at all costs.”
