The reason for Princess Beatrice's 'hands-off' Maid of Honour duties

Princess Eugenie and Jack Brooksbank tied the knot in a glorious ceremony in Windsor on Friday, marking the second Royal Wedding of the year.

However, onlookers couldn't help but notice the curious role her sister Princess Beatrice played in the lavish proceedings.

As the official maid of honour, the 30-year-old royal was expected to be the one making a fuss over the bride, but instead she seemed more concerned with her mother, Sarah Fergusson.

The Daily Mail suggests that instead of having regular bridesmaid's duties, Beatrice was tasked with accompanying her mum to St George's Chapel.

It's no secret that Fergie has been somewhat ostracised by the Royal Family since her split with Prince Andrew and subsequent media scandals.

While she attended nephew Prince Harry's wedding to Meghan Markle in May, it's been reported that she wasn't invited to the reception.

She's known as a strong and independent woman, however walking into the church on Friday by herself, with all eyes on her, would have been daunting to say the least.

So, the theory goes that daughter Beatrice was on hand for moral support, and we think it's just gorgeous.

The blushing bride had the help of her father, Prince Andrew, to fix her dress before walking her down the aisle, and 14-year-old Lady Louise Windsor rallied the young bridal party that accompanied them.

The proud sister watched on from the pews, next to a beaming mum, as their "Genie" said "I do" and married the love of her life.

Beatrice also showed her support for her sister by reading a passage from F. Scott Fitzgerald's book, The Great Gatsby, which has a strong sentimental meaning to the couple.
