While whirlwind romances are not uncommon for members of the royal family, their relationship is comparatively shorter than her decade long relationship with Dave Clark - a relationship that allegedly left her 'devastated.'

As she excitedly plans the royal wedding, her friends revealed that the joyful period is following heartbreak from her not-so-distant past.
According toPeople., Beatrice went through a painful split from American Uber executive Dave in 2016 (who then went on to marry advertising executive Lynn Anderson last year).
“She was so devastated by that, so it is really lovely to have this,” a royal insider told the publication, adding that Mozzi “is a great support to her. She just sounds so incredibly excited that she has found someone she’s thrilled about spending the rest of her life with.”
Introduced to each other by Prince William, the couple first met at a birthday party held by Sean Brosnan (the son of Pierce Brosnan) and sparks flew immediately.
People reported that Princess Beatrice was completely devoted to the mogul, even moving to San Francisco and New York to be with him while he grew the taxi app Uber.
“I think it was very hard for her when she split up with Dave, it was tough on her. And it must have been difficult as the eldest to watch her little sister go down the aisle,” a source told the publication (Princess Eugenie married Jack Brooksbank at St George's Chapel last year).
Princess Beatrice dated Uber executive Dave Clark for a decade before their split in 2016.

However, with a new fiancee on by her side, Princess Beatrice has found joy again.
"The Duke and Duchess of York are delighted to announce the engagement of Her Royal Highness Princess Beatrice of York to Mr. Edoardo Mapelli Mozzi.
"Her Royal Highness and Mr. Mapelli Mozzi became engaged while away for the weekend in Italy earlier this month. The wedding will take place in 2020. Further details will be announced in due course."
Princess Beatrice and Edoardo Mapelli Mozzi announced their engagement on Thursday the 26th of September.
Edoardo proposed to the Princess of York while they were on holiday together in the up-market Italian coastal town of Positano.
In their joint statement, the couple revealed they were "extremely happy" about the prospect of getting married: "We are extremely happy to be able to share the news of our recent engagement."
"We are both so excited to be embarking on this life adventure together and can't wait to be married. We share so many similar interests and values and we know this will stand us in great stead for the years ahead, full of love and happiness."
