Theodora Williams, the six-year-old daughter of singer Robbie Williams and his wife Ayda Field is to be a bridesmaid at the wedding of Britain's Princess Eugenie, Buckingham Palace announced on Wednesday.
The little royals are no strangers to these roles.
Meanwhile, six-year-old Louis de Givenchy, the son of Zoe and Olivier de Givenchy will be the other pageboy.
Princess Eugenie and Jack have also opted to break tradition with their wedding cake, opting for an autumnal red velvet and chocolate confection instead of customary iced fruit cake.More news: Liverpool and United in transfer fight for Ramsey

Groom Jack Brooksbank has asked his brother, Thomas Brooksbank, to be his best man, while Eugenie's older sister Princess Beatrice will be her maid of honour. Prince Edward's children, 14-year-old Lady Louise Windsor and 10-year-old Viscount Severn will be special attendants.
It's reported that Eugenie has asked guests not to bring their cell phones or any cameras because "photography is not allowed in St George's Chapel or Windsor Castle".
"After the ceremony, ITV will return to This Morning and Eamonn and Ruth will be live with comments, discussion, and reflection on the events of the morning".
The couple, who exchanged vows in May at Windsor Castle, have spent their first few months as a married couple finding their feet in public life and developing celebrity friendships with A-listers like George and Amal Clooney.
Five of them will be royal, but the other will be showbusiness royalty.
Jack proposed to Eugenie, whose mum is Sarah, the Duchess of York, with a padparadscha sapphire ring surrounded by diamonds. Do you plan on watching the wedding?
