Prince William back in the pilot seat as Kate celebrates her birthday

Just days after her big day on January 9, Kate will pay a visit to a special community garden in London, Kensington Palace revealed - and it's quite similar to her first outing back from maternity leave previous year.

Prince William, a former pilot with the air ambulance service in East Anglia, flew from Kensington Palace for 25 minutes before landing on a helipad at the Royal London Hospital.

During the event William was given a card to mark his wife's birthday, to which he said: "I did remember this morning - so I was OK".

But when quizzed about what he had given his wife as a gift, he laughed off the question.

English also shared a close-up of the card that the children made, which reads: "To Princess Kate, I hope you've had the best birthday you could ever imagine".

The palace wished Middleton a happy birthday on the palace and the royal family's official Twitter accounts.

"She'd already had it the week before at Kensington Palace, as ludicrous as that might have been", the expert continued.

Kate has also become an aunt to sister Pippa Matthews's baby son Arthur, and the Cambridges are also awaiting the arrival of the Duke and Duchess of Sussex's first child in the spring - another cousin for George, Charlotte and Louis.

Kate has had a busy 12 months on the family front, giving birth to Louis last April and becoming a mother of three.

William, who worked as an air ambulance pilot for many years, has previously spoken about how his job impacted his mental health.

The duchess was born in Reading on 9 January 1982, to Carole and Michael Middleton.

At the age of 13, she went to the exclusive, private Marlborough College in Wiltshire, where she part-boarded.

The duchess-to-be met and began dating William while studying art history at St Andrew's University, where she studied history of art.
