Princess Beatrice beams with cousin Zara Tindall at Monaco Grand Prix

Princess Beatrice, 35, and Zara, 43, posed with the TV presenter at the glamorous event.

The Princess of York and Pinkham could be seen kissing Zara on the cheeks, as the Olympic equestrian posed in the middle.

Princess Beatrice wore an Alice and Olivia denim jacket which she paired with Soek sunglasses that cost £49.99.

According to the Royal Fashion Police on Instagram, these sunglasses belong to Zara, showing the close bond between the cousins.

As well as being friends with Beatrice and Zara, Pinkham was also once reported to be linked romantically to Prince Harry.

In 2003, when Prince Harry was just 19, the young royal was reported to be romantically linked to Pinkham.

She previously said: "I realised very quickly what a normal bloke he was."

The Duke of Sussex was understood to be "head over heels" for the sports presenter.

The two never publicly confirmed a romantic relationship, and Harry did not mention Pinkham in Spare.

However, they reportedly maintained a friendship years after being linked together.

Another high-profile royal who stunned at the Monaco Grand Prix was Charlene, Princess of Monaco.

The 46-year-old wore a blue jumpsuit as she posed beside her husband, Prince Albert of Monaco.

The duo usually attend the high-profile sporting event every year as the heads of the House of Grimaldi.
