Everyone can't stop talking about Kate Middleton and Meghan Markle, but the fashion world is fawning over Princess Diana's 27-year-old niece, Lady Kitty Spencer. 

Lady Spencer's father is Charles Spencer, Princess Diana's younger brother, and her mother is former model Victoria Aitken. This makes her Prince Harry and Prince William's first cousin.

Born in the UK, raised in South Africa, Lady Spencer now lives in London, where she works as a professional model. The 27-year-old spoke to INSIDER all about her glamorous life, although she declined to comment on any matters regarding the royal family.

Lady Spencer landed her first magazine cover when she was a baby.

At 1 year old, Lady Spencer graced the cover of Harper's & Queen (now known as Harper's Bazaar UK) in 1992 with her mother. Lady Spencer told INSIDER that this was her first experience in front of the camera and her first time on a magazine cover.

"When I was growing up, when I had a list of things I wanted to be, I never thought a model," she said.

Although she was scouted by agencies while she was in school, her mother always protected her and encouraged her to focus on academics instead. Lady Spencer respected her mom's choice and said she was happy to put school first.

She eventually made her way back to the fashion world.

To continue her education, Lady Spencer headed to London, where she earned her master's degree in Luxury Brand Management at Regent's University London.

While living in the city, she began to casually take modeling jobs and fashion naturally became a big part of her life. 

Now, Lady Spencer is represented by Storm Model Management, the same agency that once represented top models like Kate Moss and Cara Delevingne. 

In February 2017, she walked her first runway for Dolce & Gabbana.

Eventually, she was approached to walk for Dolce & Gabbana's February 2017 runway show during Milan Fashion Week. Lady Spencer said that walking the catwalk for one of the most iconic brands was an "exhilarating, out of body experience."

This fashion show was a major step in her modeling career and, on a personal level, it inspired her to be more confident.

Lady Spencer has been a muse for the designer ever since.

Since her first show, Lady Spencer returned to the catwalk for Dolce & Gabbana's "Secret Show" in September 2017, and most recently, in its "Secrets & Diamonds" show in February 2018. 

Spencer wasn't the only famous face on the Dolce & Gabbana catwalk. Ladies Violet, Alice, and Eliza Manners, the daughters of the Duke and Duchess of Rutland, walked in the "Secrets & Diamonds" fashion show, too. 

The model has enjoyed working with the designer since she was cast in her first show last year.

"It's such a time now where individuality and diversity are celebrated, and if there's ever a brand that knows how to appreciate and celebrate a woman's shape, it's Dolce & Gabbana," she said.

Lady Spencer's portfolio extends beyond the runway.

In addition to her runway work, Lady Spencer has also been featured in major campaigns and editorial spreads. She's previously modeled for international magazines like Marie Claire España and Elle Russia. 

She also appeared in Dolce & Gabbana's spring/summer 2018 eyewear campaign, which was shot in Venice, Italy, according to pictures from her Instagram.

 Most recently, she was named an official UK ambassador to the jewelry brand Bulgari.

She has a unique sense of style.

Lady Spencer's personal sense of style is constantly changing. "My confidence levels or where I am in my life very much influenced my style," she told us. For example, she described her hometown of Cape Town as a very relaxed environment and said there isn't much of an emphasis on fashion there.

But when she moved to London, where it's very fashion forward, she stopped playing it safe. "I think only over the past year or so did I really feel like I've engaged with fashion or style to have fun and express who I am through what I wear," she said.

She sees her personal style as a learning experience, but told us that she likes to wear things that are both classic and feminine. Her floral dress for the Kate Spade fall 2018 presentation perfectly captures this charm.

Lady Spencer said that she also likes "bold colors and fun jewelry, or just something that adds a touch of irreverence," which is evident from her fun Dolce & Gabbana look at Paper Magazine's Beautiful People party during New York Fashion Week in 2017.

She is seriously down to earth. 

When she's not walking the runway or sitting front row at Fashion Week, Lady Spencer spends her time focusing on her other passions, namely travel and charity work.

Lady Spencer spent three years studying art in Florence, Italy — which she calls "the most magical place in the world"— before moving to London. "It was just like living in a dream," she said of her time in the Italian city.

Lady Spencer also acknowledged that one of the most rewarding aspects of her role as a public figure in the fashion industry is being able to help others. "I think the greatest thing is that it gives me the platform to speak up about the causes that matter to me," she said.

One of those causes is Give Us Time, a military charity that she has worked with since 2013. This year, the charity announced that she was appointed as a patron.

For the last three years, Lady Spencer has also been involved with Centrepoint, a charity that aims to raise awareness and funds for thousands of homeless youth. 

She recognizes that the two organizations are different in many ways, but at the core, she said, they are both focused on "nurturing the family unit," a subject that she really cares about. "Family is hugely important to me," she said.

With her well-rounded sense of sincerity, passion, and budding career, Lady Spencer is one to watch.
