Princess Eugenie and Jack Brooksbank have announced they will have a "modern" red velvet and chocolate wedding cake.
The couple, who are set to marry at St George's Chapel in Windsor Castle on 12 October – the same venue in which Prince Harry wed Meghan Markle in May – have announced new details of their big day.
Following in Harry's footsteps, the couple will forego the traditional fruit cake enjoyed at royal weddings since the Victorian era for something more contemporary.
They have asked London-based cake designer Sophie Cabot to make their wedding cake, which is described as being "traditional with a modern feel".

It will incorporate the rich colours of autumn in its design and will be covered with detailed sugar work including ivy.
Ms Cabot began her bespoke cake design business in 2014 after growing up with a love of bakery – learning her skills from her grandmother and mother.
Eugenie – who is the youngest daughter of Prince Andrew and Sarah, Duchess of York – and Mr Brooksbank, are said to be delighted that Ms Cabot can be involved in their celebrations for the special day.
"I am incredibly excited to be given this wonderful opportunity to create such a special and unique cake," Ms Cabot said.
"It has been lovely working with Princess Eugenie and Jack and I really hope they enjoy the cake on the day."
Harry and Meghan paved the way in breaking off from royal tradition, opting for an organic lemon elderflower cake by pastry chef and food writer Claire Ptak for their 19 May wedding.

In a gesture inspired by the Duke and Duchess of Sussex's spring wedding, 1,200 members of the public have been invited into the castle grounds to enjoy the occasion.
Eugenie and Mr Brooksbank, who became engaged in Nicaragua in January, have also announced that internationally renowned singer-songwriter Andrea Bocelli will perform two pieces during the service.
State trumpeters from the Band of the Household Cavalry are also set to perform a fanfare during the ceremony, as well as musicians from the Royal Philharmonic Orchestra (RPO).
