Eugenie’s wedding bouquet has been laid on the Grave of the Unknown Warrior in Westminster Abbey.Princess Eugenie and new husband Jack Brooksbank are understood to be continuing their celebrations the day after their lavish wedding.

The pair sealed their union with two kisses on Friday, before gathering at an afternoon reception in Windsor Castle and an evening party at the York family home Royal Lodge in Windsor Great Park near London.

Pop warbler Robbie Williams reportedly treated guests to some of his greatest hits, after watching his daughter Theodora, known as Teddy, perform bridesmaid duties at St George’s Chapel that morning.

Meanwhile, Eugenie’s bouquet was laid on the Grave of the Unknown Warrior in Westminster Abbey on Saturday.

The couple were believed to be continuing festivities with friends into the weekend.

Eugenie, who is ninth in line to the throne, and tequila brand ambassador Jack said their vows in front of a star-studded congregation of 800 people.

Watching in the historic 15th-century chapel of the castle were the Queen, the Duke of Edinburgh, and more than 40 members of the royal family including the Prince of Wales, the Duke and Duchess of Cambridge and the Duke and Duchess of Sussex.

Celebrities in attendance included Hollywood actresses Liv Tyler and Demi Moore, supermodels Kate Moss and Naomi Campbell, singers Ricky Martin, Ellie Goulding and James Blunt, broadcaster Stephen Fry, and artist Tracey Emin.

Eugenie’s sophisticated dress, which featured wide fold-over shoulders, a low back and full-flowing train, was by Peter Pilotto and Christopher De Vos, while she wore the Greville Emerald Kokoshnik Tiara loaned to her by her grandmother.

After the ceremony, the happy couple waved to well-wishers during a carriage procession through Windsor, before heading to their afternoon reception hosted by the Queen.

The Duke of York was said to have given a traditional father-of-the-bride speech, and reportedly teased Jack with a joke about the family dog before embracing his new son-in-law.

The royal family expressed gratitude to all those who enjoyed the wedding, saying on the official Twitter account: “Thank you to everyone for watching and joining in with the #RoyalWedding celebrations – Congratulations once again to the happy couple!”
