Kate Middleton was born on January 9, 1982, meaning this year she turns 38-years-old.
The Duchess of Cambridge is the oldest member of her immediate family and has a few months on Prince William.
She is nearly six months older than her husband, who was born on June 21, 1982.
In 2020 the Duchess marks her ninth birthday within the ranks of the Royal Family, and this year she celebrated like a royal.
Although she officially turns 38 today, she celebrated her birthday last weekend.
According to PEOPLE Magazine, while Kate began the day by attending a church service with hers and William’s family, she enjoyed a party in the evening.
Kate and William hosted a gathering at their Norfolk residence of Anmer Hall, attended by a selection of high-profile guests.
In 2020, Kate will enjoy a second year of dual celebration, as she did the same last year.
