If there is any truth to the reports, Hutchins would be Jenner's fourth wife.So what do you need to know about her potential new wife?
Who is Sophia Hutchins?
Sophia Hutchins is a 21-year-old aspiring model who has been spending a lot of time with Caitlyn Jenner as of late. She is a student at Pepperdine University, which isn't far from where her rumoured reality star fiancee lives.
She was said to be studying finance, though she's since removed that from her Instagram.
Hutchins is also transgender and has been open about her experience as a transwoman. In 2016, she told her school newspaper Jenner inspired her to transition.
She told the paper that seeing the 20/20 special about Jenner's transition "made it so much more real" for her.
Speaking on her own transition at the time, Hutchins said: "I've always had the question of, 'Do I want to transition from male to female?' I never thought a lot about doing it until I got into college because I was able to break away from my family and started to establish my own identity.
"College gave me the time to deal with a lot of issues that had always been there."
It's unclear exactly how Jenner and Hutchins met, but the pair spend a lot of time together. They've been photographed at car races, red carpet events and celebrity bashes.
The Mirror reported that Jenner whisked Hutchins away on a trip to Mexico last year, cementing their status as a couple.
They're now thought to be living together.
Signs Caitlyn Jenner's about to tie the knot
An anonymous insider told Radar Online: "They consider each other soul mates and freely admit they couldn't imagine a life with anyone else at this point."
Sources have said the pair are planning an intimate wedding at Jenner's Malibu, California, but Radar Online reports the nuptials will take place on a bluff near Jenner's sprawling pad.
She and Hutchins will reportedly wear wedding gowns on the big day and carry bouquets.
"Cait has a wedding planner to handle all the details," a source said.
The insider added: "This is a dream come true for Cait because her rejection by the Kardashians — and even her own daughters — had left her feeling isolated and suffering from a crippling depression. Sophia has changed all that."
Sophia Hutchins' Instagram
Sophia Hutchins' Instagram is full of selfies, beach photos, modelling shots and pictures of her beloved dog - and many of the photos are taken at Jenner's home. There are also plenty of photos of the pair together.
Hutchins previously showed support for Kylie Jenner on her Instagram page, showing off her massive stash of Kylie Cosmetics. However there are no telling signs that she and Kylie have any kind of relationship.
