Prince William and Kate Middleton delighted royal fans as they extended heartfelt 40th birthday wishes to Prince Harry.

On September 15, the Prince and Princess of Wales re-shared the royal family's birthday tribute post and penned a touching message for the Duke of Sussex. 

The royal couple wrote, "Wishing a Happy 40th Birthday to The Duke of Sussex."

Notably, William and Kate's message came after King Charles released a statement to mark Harry's milestone event. 

The royal family seemingly dropped a major sign of reconciliation with the estranged member of the Firm as they put aside their differences for the Duke of Sussex's big day. 

Now, the royal fans are anticipating a response from Harry after his family hinted at their future reunion.
