In an interview with Town and Country in May, Spencer said discussing her love life in public leaves her feeling "vulnerable." "I just think, 'Really, what's that got to do with anyone else?' It shouldn't make a difference to anyone's day. Who I love or don't love, or have a crush on or don't have a crush on, or go on a date with, I don't know why that should be what somebody reads over their cornflakes," Spencer said. "As long as I keep it sacred, then it can remain so. As soon as I don't, I don't think you can get it back."

It's because, for me, love is the most important thing in the world, and I will protect it with all my heart by not making it a topic of discussion. You open yourself up to other people having opinions, and it just isn't relevant to anybody's life but mine and my family's." Can't get enough of PEOPLE's Royals coverage?

On top of studying in Florence for three years, the model made her catwalk debut for Dolce & Gabbana in 2017, though she almost declined the offer. "It was terrifying!" she told Town and Country. "I was 26 and working full-time for a charity, and I loved it, but it's very different from that world of style. I went home and spoke to my family, and my mum said, 'Well, why don't you?'"
