Sophia Hutchins and Caitlyn Jenner had an extremely close friendship before the former died in a shocking accident.

On Wednesday, the 29-year-old was driving an ATV near Jenner’s Malibu, Calif., mansion when she hit the bumper of a moving vehicle.

The collision threw Hutchins down a 350-foot ravine, where she was pronounced dead at the scene.

Jenner has yet to issue a statement regarding Hutchins’ tragic passing.

The duo enjoyed a decade of friendship, with Hutchins describing the retired athlete as her “partner” in life in 2018.

Revisit their relationship below.

2015

In 2015, Hutchins and Jenner were introduced by their shared hairstylist and makeup artist, coinciding with the year that the “Keeping Up With the Kardashians” star publicly embraced her transgender identity.

During an interview with listeners of the “Juicy Scoop” podcast in 2020, Hutchins recounted, “He was doing my hair one day and he said, ‘I’m going to a photoshoot right after this and Caitlyn is going to be there and Caitlyn would like to meet you.’”

She noted that the duo immediately “got really close as friends.”

2016

In 2016, Hutchins credited her Olympian pal as inspiring her own transition.

Jenner “made it so much more real,” the Pepperdine University student wrote in a research article for the university.

She further expressed, “Like, normal and successful people do this and people are OK when they do it,” highlighting her background in finance and economics, having graduated from the university with a degree in these fields.

2017

Hutchins became Jenner’s manager in 2017 — a role previously filled by the reality star’s ex-wife Kris Jenner.

“I learned a lot about what was going on in Caitlyn’s life and I just felt it was a financial s—tshow — so much money was being thrown everywhere — and nobody was really running the show,” Hutchins explained to Heather McDonald in 2020.

“She didn’t have a manager,” she continued. “Kris wasn’t doing it anymore since they divorced and I felt I could do a really good job.”

As the duo made headlines for outings together in 2017, Jenner’s rep insisted to Page Six that the pair were “just friends.”

2018

Hutchins confirmed their platonic status the following year by replying with an eye-roll emoji when an Instagram user asked whether she was dating Jenner.

She elaborated in a “Hidden Truth” podcast interview, saying, “I would not say we’re dating. I would say we’re partners. I would not use the word ‘girlfriend.’ I would not say the word ‘dating.’”

“We’re partners in everything we do,” she continued. “We’re inseparable. We’re business partners. We live together. We share a dog. We share family, we share a life together. We’re not going to [label it].”

After Hutchins referred to them as “two souls that are a fantastic match,” the pals continued to put their friendship on display, from Mexico trips to joint Fashion Week appearances.

2019

Hutchins was present in October 2019 when Jenner celebrated her 70th birthday with a family-filled bash.

When Jenner joined “I’m a Celebrity … Get Me Out of Here” that same year, Hutchins felt “weird” celebrating Thanksgiving without her.

“I’m hosting it at our house with some of my family and my good friend and his family, so it’s going to be different this year,” she told Page Six at the time.

Hutchins confirmed to the New York Times in December 2019 that she and Jenner were “never romantically involved.”

2020

In Hutchins’ “Juicy Scoop” interview, she also revealed Jenner once walked in on with her with a guy, whom Jenner allegedly “knew was there.”

She claimed, “We had to put a lock on my door because Caitlyn decided to barge into my room while I had a friend over. It’s kind of like living with your parents and I’m like oh, this might be a turning point where I might need to move out.”

“I don’t want to leave her by herself, but she also knows that I’m getting older and I want to be able to have my own life,” Hutchins added.

2021

Hutchins insisted again in 2021 that she and Jenner had a platonic dynamic.

“There’s no hanky panky,” she told People at the time. “I feel like I’ve been saying that for the past five years.”

At the time, Hutchins compared the “I Am Cait” alum to her parent.

2022

When Hutchins and Jenner appeared on the “Full Send” podcast in 2022, the latter called Hutchins “the most amazing” and “smartest person.”

Jenner added that Hutchins is “the brains behind” her career.

For Jenner’s birthday that year, Hutchins called her “the best … mentor, chosen family [and] the most genuine human being” in a touching Instagram tribute.

2023

Hutchins continued giving glimpses of her life with Jenner via social media.

In 2023, she joked about needing to “golf with worse people” after playing with Jenner and “getting [her] ass kicked.”

2024

Hutchins, a political surrogate for President Donald Trump’s 2024 campaign, blasted the LGBTQ+ community that year as “toxic” and “bulls–t” — and Jenner made headlines for defending her against backlash.

The former track star agreed in June 2024 that the community is “a joke.”

Four months later, Hutchins attended Jenner’s birthday party.

2025

Jenner’s social media was flooded with condolences after Hutchins died.

Her late pal’s final social media upload, posted in April 2025, was about “healing.”

Hutchins fixed a broken candelabra in before-and-after photos at the time, jokingly referring to herself as “Dr. Hutchins.”
