Meanwhile, the Valentine’s Day announcement came just days after the royals welcomed another baby to the family.
Princess Eugenie gave birth to her first child earlier this week.
Buckingham Palace announced the arrival of Eugenie’s baby, revealing that the Princess’s son weighed 8lbs 1oz at birth.
A statement read: “Her Royal Highness Princess Eugenie was safely delivered of a son today, 9th February 2021, at 0855hrs at The Portland Hospital.
“The Queen, The Duke of Edinburgh, The Duke of York, Sarah, Duchess of York, and Mr and Mrs George Brooksbank have been informed and are delighted with the news.”
