Princess Eugenie has just revealed a very important wedding detail

And it’s pretty groundbreaking.

2018 is undoubtedly the year for royal weddings, with Prince Harry and Meghan Markle tying the knot in May and Princess Eugenie set to wed her partner Jack Brooksbank in October.

While the millennial couples are reported to be very close – living just a stone’s throw from each other in Kensington Palace, sharing a wedding year is undoubtedly making them even closer, with Princess Eugenie reportedly taking a few leaves out of the Duke and Duchess of Sussex’s book.

Eugenie and Jack’s impending nuptials are taking place at St George’s Chapel, Windsor Castle, the very same venue as Harry and Meghan – and like the newlyweds, the young couple are set to have some famous faces in the pews.

While royals from Kate Middleton and Prince William to Prince Harry and Meghan Markle will of course be in attendance, it is expected that we will see celebrity pals from James Blunt, Pippa Middleton and Jack Whitehall to Jimmy Carr and Cara Delevingne in attendance.

But the key guest list similarity between the two ceremonies is the invitations, with both couples expanding their guest lists to invite members of the public to their big day.

Another connection between the two ceremonies was announced recently as Princess Eugenie announced that the day would be environmentally friendly.

But while Prince Harry and Meghan Markle sent their environmental message with the choice of an electric wedding car, Princess Eugenie and Jack Brooksbank are taking it a step further - implementing a no plastic rule at their wedding.

That’s right, the royal couple are banning plastic from their big day, with 28-year-old Eugenie being an Ambassador of Project O whose aim is to restore and protect the ocean.

‘My whole house is anti-plastic now,’ Eugenie revealed to Vogue in a recent interview. ’And Jack and I want our wedding to be like that as well.’

Speaking of the impending nuptials, she explained to the publication, ‘It's very nerve-wracking because you want it to be perfect but then you realise that you're going to be with the person you love forever and nothing else really matters.’

We can’t wait for the wedding.
