Her Royal Highness and Brooksbank have been together for seven years, and announced their engagement last month. The lovebirds released a series of engagement photos, highlighting Princess Eugenie's stunning pink padparadscha sapphire ring.
They also gave their first post-engagement interview, where Princess Eugenie gushed over Brooksbank's romantic proposal at a lake in Nicaragua at sunset.
"The lake was so beautiful," she recalled. "The lake had a special light I’d never seen. I actually said, 'This is an incredible moment,' and then he popped the question. I was over the moon, crying."
This will mark the second royal wedding of 2018, as Prince Harry will say "I do" to Meghan Markle on May 19 at the same venue.
The two have been busy preparing for the ceremony, while still making time for their scheduled appearances. They were last spotted together in London, rocking coordinating suits and flashing smiles while attending the annual Endeavour Fund Awards at Goldsmiths' Hall.
