Princess Beatrice and Edoardo Mapelli Mozzi stepped out as a newly engaged couple this weekend, and it just so happened to be a royal wedding.

On Saturday, they took a break from planning their own upcoming nuptials [1] to attend another royal wedding. They celebrated the marriage of Jean-Christophe, Prince Napoléon (a descendant of Napoleon Bonaparte) and Countess Olympia von Arco-Zinneberg (great-great-great niece of Napoleon's second wife) at Les Invalides in Paris. We've seen the couple a few times this month following the announcement, including a stylish night out [2], attending the premiere of The Elephant Queen and now, a royal wedding as husband-and-wife-to-be.

For the special occasion, Princess Beatrice looked radiant wearing a pastel-coloured floral dress, light blue coat, and blush pink hat; if this ensemble is anything to go by, we're in for a treat when it comes to her wedding dress.

The pair got engaged in September [3] after a year of dating, with the wedding set to take place in 2020. Until then, get a closer look at the happy couple attending the ceremony.
