When Princess Beatrice celebrates her 31st birthday next month it will be commemorated with an all-vegan birthday bash.

The Princess recently returned home to London after living in New York and with the change of location came a change in diet and lifestyle. The party will be catered by The Admirable Crichton and will include a fully vegan three-course dinner and a dairy-free birthday cake.

Beatrice isn’t the only royal with an interest in veganism. Both Meghan Markle and Lady Amelia Windsor have recently shown an interest in eating a plant-based diet. The party is expected to be attended by other members of the royal family, including Beatrice’s sister, Princess Eugenie.
