Traditionally, Kate Middleton prefers a low-key celebration, often commemorating the occasion at her and Prince William's country residence, Anmer Hall, in Norfolk.
The insider noted, "To be honest, that's just the way she likes it." In previous years, the Wales family has been seen attending mass at St. Mary Magdalene church on the Sandringham estate during birthday weekends.
Additionally, Prince William hosts an intimate tea party in honor of Kate's birthday, a tradition observed in 2021. A source shared with People, "If you go round to her house, you get a cup of tea, and it's often William who makes it! It's a lovely, welcoming house, not a fancy, stuffy palace in any way."
The mom of three can expect birthday wishes from senior royals, including King Charles and Queen Camilla, who expressed their sentiments via a thoughtful social media post last year.
To mark the royal's birthday, residents of London will also hear bells ringing at Westminster Abbey next week, adding a touch of celebration to the special day.
