Princess Eugenie and Jack Brooksbank are set to get married in the coming autumn five months after her cousin Prince Harry walked down the aisle with actor Meghan Markel.
The family later announced that the wedding is set to happen on October 12.
The wedding comes shortly after Prince Harry got married to Meghan Markel earlier this year. Prince Harry and Princess Eugenie are first cousins.
The couple is inviting members of the public to attend their wedding. Approximately 1200 people are invited to attend the wedding. The selection of the attendees will be done partially through a ballot and people are allowed to apply online.
The list of attendees will include Windsor castle community members, members of the royal house, charity workers, children, and other people with close relationship with Eugenie.
The wedding will take place at the St Georges chapel, the same venue in which Prince Harry and Meghan Markel got married earlier this year. The chapel is located in the Windsor Castle perimeters where the Queen resides most times of the year.
The venue is smaller than the Westminster Abbey where Prince William and Kate Middle stone got married years ago. It can hold 800 seats compared to 2000, which the Westminster can accommodate.
Prince Harry and Meghan Markel are also invited to the wedding as special guests. Applicants who want to attend the wedding must be 5 years or older. An adult should accompany children under the age of 16.
The application is only viable for people living in the UK only. The 1200 lucky people will get to witness the live proceedings and commentary of the wedding in the Windsor castle.
Princess Eugenie and Jack Brooksbank have dated for a long time. She is the daughter of Prince Andrew, the Duke of York and ninth in line for the throne.
The palace will communicate more information about the wedding in the meantime.
