SPORTY, INTELLIGENT AND SHOWING AN IMPRESSIVE SENSE OF STYLE LADY LOUISE SHINES LIKE A JEWEL IN THE ROYAL CROWN AS SHE TURNS 21

As she celebrates her 21st birthday this week, Lady Louise Mountbatten Windsor is growing up into an engaging young woman.

The elder child of the Duke and Duchess of Edinburgh has conducted herself with elegance and grace at public events in recent years, all while continuing her studies at a prestigious university.

And as she approaches her next chapter, Louise's interests are becoming clear: she is passionate about carriage driving and also has an interest in the armed forces.

While studying English literature at St Andrews University, she has joined the Officers' Training Corps, which provides paid military training for students.

She's also gaining close friendships, with fellow student Felix da Silva-Clamp a prominent presence by her side when she took part in the Sandringham Horse Driving Trials in June.

All the while, she has been supporting her family at royal events, including the King's coronation in May last year.
