Dara Huang, who shares a son with with Mr Mapelli Mozzi, was seen enjoying dinner out with friends in Knightsbridge, west London, just hours after the royal wedding on Friday. Pictures show Ms Huang laughing and looking relaxed with friends while eating in an outdoor area.
She was spotted just a few hours after Princess Beatrice married the property tycoon Mr Mapelli Mozzi.
The secret ceremony was held at the Royal Chapel of All Saints at Royal Lodge, Windsor.
The Queen and Prince Philip attended the wedding with a small amount of guests.
Mr Mapelli Mozzi’s son, Christopher Woolf, was his best man and page boy at the wedding.
It is not known if Ms Huang attended the wedding.
She later left her friends carrying a coffee and a shopping bag according to the Sun.
Ms Huang also shared a photograph on Instagram of herself playing tennis on the same day of the royal wedding.
She was engaged to Mr Mapelli Mozzi for three and a half years before they broke up in 2018.
In a statement Buckingham Palace said: “Her Royal Highness Princess Beatrice of York and Mr Mapelli Mozzi have been touched by the warm wishes they have received since their wedding, and are delighted to share two additional photographs of their happy day.”
One photograph showed the newly weds leaving the chapel through a flower covered archway.
Another photograph portrays the couple outside the entrance with Princess Beatrice’s grandparents, the Queen and the Duke of Edinburgh.
None of the photographs released show Princess Beatrice’s parents, the Duke and Duchess of York.
The palace has confirmed her father, Prince Andrew, walked Princess Beatrice down the aisle.
The Queen loaned the bride a vintage dress for the wedding.
Her Majesty also loaned a diamond fringe tiara which the monarch wore on her own wedding day in 1947.
Princess Beatrice and Mr Mapelli Mozzi originally planned to marry in May but had to postpone due to the coronavirus pandemic.
When the nation went into lockdown in March, weddings in England were banned.
But since the start of July, ceremonies of up to 30 people have been allowed to take place.
