Caitlyn Jenner (formerly known as Bruce Jenner) first gained recognition for becoming a gold medal-winning Olympic athlete when she won the men’s decathlon event at the 1976 Summer Olympics in Montreal. She later found fame as the husband of Kris Jenner, a step-father to the Kardashian kids and a dad to Kendall and Kylie Jenner. Since transitioning in 2015 and divorcing Kris, a lot has changed in Caitlyn’s life.

Not only is she going by a new name, but her relationship with her family has gone through quite the dramatic transformation. She’s also had a new love interest for the past few years and has become an outspoken advocate for issues close to her heart. Keep on reading to see just how much Cait’s life has changed in recent years.

15 She Missed Her Son’s Wedding (And He’s Upset)

Last year, Caitlyn’s son Brody Jenner married his long-time love Kaitlynn Carter. But it didn’t take fans long to realize there was one important person missing from the nuptials - Caitlyn!

“The people who didn’t get to go, are they going to be sent a video or something?” a TMZ reporter asked the couple, to which Kaitlynn responded, “They should have gone if they wanted to see it!”

14 She’s Not Close To Any Of Her Kids, In Fact

Caitlyn has been open about her strained relationship with her six children. Just last year, the former athlete made it clear she has little to do with her now grown kids.

“I have a lot of children, but sometimes just because of circumstances, maintaining a close relationship with your kids is very tough,” she told Broadly. “They've all moved on.”

13 She Had A (Very) Public Argument With Kendall

Although the Kardashians usually like to handle their drama in private, just last year Kendall couldn’t help but lose it with her dad when they ran into each other at Nobu Malibu.

“They were arguing,” a source told Page Six. “It was more Kendall ripping Caitlyn a new one for ‘always turning her back on the family’ after they’ve been so good to her.”

It’s unclear if Caitlyn and Kendall have made up yet.

12 Her Girlfriend Is 47 Years Younger Than Her

It would already be weird if Caitlyn was dating someone the age of her former Kardashian step-children. But she’s actually dating someone who’s the same age as her youngest daughters, Kendall and Kylie.

The celebrity has been dating student Sophia Hutchins, who’s also transitioned, for the last few years. Sophia is 47 years younger than Caitlyn, as she’s only 23 while Cait is 69 years old.

11 The Kardashians Have Defended Their Relationship

While fans are still unsure what to think of the unlikely romance between Caitlyn and Sophia, Khloe Kardashian actually defended them just last May.

“She’s really sweet. She’s younger, but she’s not bothering anyone. She’s super sweet,” Khloe told Laura Wasser, Hollywood Life reports.

Given that Momager Kris is dating someone 30 years her junior, the Kardashians are likely used to these huge age gaps.

10 She Finally Settled Her Infamous Car Crash Suit

In 2015, Caitlyn got into a car accident after she rear-ended the car in front of her, which was carrying a family of five. The celebrity’s legal team has been trying to resolve the situation since then, and just last year it was reported they’d agreed to a settlement.

Caitlyn agreed to pay a total of $800,000 to prevent the case going to court, ABC News confirms.

9 She Underwent Reassignment (But Kept It A Secret)

Caitlyn is now open about the fact that she had a gender reassignment procedure done in 2017, but at first she says she told no one - not even the Kardashians.

“No, I didn’t tell anybody. It’s none of their business. No, it’s not that big a deal,” she told Piers Morgan last year, adding she was worried the Kardashians would leak it to the tabloids.

8 She Dissed Stormi’s 1^st Birthday Party

Back in February, Kylie Jenner threw her daughter Stormi a very elaborate party to celebrate her first birthday. Even though Caitlyn attended, it didn’t sound like she was too impressed with the lavish event.

"We just left Stormi's first birthday," she told E! News, describing the party as being OTT. "My family's very good at that," Cait added.

7 She’s Finally On Speaking Terms With The Kardashians

Kardashian fans know the famous family has been on the outs with Caitlyn ever since she had a few choice words for Kris. However, it sounds like they’re all finally speaking again.

At the very least, she and Khloe are on good terms. “Caitlyn and Khloe had a huge breakthrough a few months ago,” a source told Hollywood Life. “They had a long heart to heart that changed it all.”

6 But She Barely Has Anything To Do With Kris

Even though Caitlyn is now communicating with her former stepchildren, things still aren’t healed between her and her ex-wife Kris Jenner.

“Kris and Caitlyn interact when they have to for the kids,” a source told People last year. “It’s important for Kylie and Kendall. They can be cordial, but like most exes, they’re never going to be best friends.”

The exes have been spotted at family events together, including last year’s annual Kardashian Christmas bash.

5 She Might Be Going Back To Reality TV

Since she kissed Keeping Up with the Kardashians goodbye years ago, not many fans have expected Caitlyn to get back in front of the camera. But there has been talk that she may make an appearance on The Hills reboot, which will feature her son, Brody.

“I don’t think so. Well — You never know!” cast member Frankie Delgado recently said of the possibility, Hollywood Life confirms.

4 The Grandkids Call Caitlyn ‘Grandma’

Since Kendall and Kylie still refer to Caitlyn as ‘Dad,’ despite her transitioning years ago, many fans assume the celebrity’s grandchildren may still call her ‘grandpa.’

However, it’s been revealed that the little ones are now used to calling her ‘Grandma.’ Fans have noticed this on various episodes of KUWTK in recent years, Daily Mail reports.

3 She’s Become An Advocate For Mental Health

Caitlyn has always spoken out about issues close to her heart, and earlier this year she discussed the portrayal of mental health in film and TV.

“A new report from [Annenberg Inclusion Initiative] shows the lack of representation of mental health depicted in popular media,” she wrote online alongside a photo of herself attending a USC panel on the topic.

2 She Overcame A Deep Depression

Since coming out, Caitlyn says her mental health has greatly improved. But before that, the media scrutiny proved almost too much to bear.

"For years, I had all sorts of issues with the tabloids and the paparazzi," she told Channel 4 News, adding that the depression almost caused her to take her own life.

1 She Has No Regrets About How She Came Out

The way Caitlyn handled her transition drove a wedge between her and the Kardashians, particularly over what she had to say in her autobiography. But the celebrity says she has no regrets.

“I know my kids... [they] thought, ‘You know what? It’s a little too much,’” she told ABC News about her Vogue cover shoot. “But from my standpoint, I had [lived in secret] for 65 years, OK? To have a beautiful shot of my authentic self was important.”
