Reality TV sensation Caitlyn Jenner first became a household name in 2015, after she came out as a transgender woman in April that year.
The TV star's $3.5 million home was the backdrop for her iconic Vanity Fair cover, where she unveiled herself as Caitlyn for the very first time.
She has since gone on to become the most famous transgender woman in the world.
Before her transition, Caitlyn - then known as Bruce Jenner - rose to the limelight as a 26-year-old Olympic champion in the 1970s.
Bruce spent years in the public eye as a heroic American athlete, before becoming part of the globally famous Kardashian empire.
The former Keeping Up With The Kardashians star, 70, has experienced her fair share of marriages, divorces, children and scandals over the years.
Let's take a look.
Chrystie Crownover
After graduating from university, Caitlyn married her first wife Chrystie Crownover (now Chrystie Scott.)
Proud wife Chrystie, who'd supported Bruce's amateur athletic career through two summer Olympics, was there to see her partner break records and win gold in Montreal in 1976.
The pair welcomed two children, son Burt and daughter Casey, but divorced in 1980 after nine years of marriage.
During her tell-all interview with Diane Sawyer in 2015, Caitlyn revealed both her first and second wives knew about Bruce's secret.
She confessed: "Chrystie was the first one to know. I said these are my issues, this is what I deal with."
Caitlyn told Dianne how she married Chrystie straight out of school, and she was the first person Caitlyn trusted with her gender issues and cross-dressing.
Speaking to GMA in an interview in 2015, Chrystie revealed her ex-husband told her she wanted to be a woman and she decided to keep Caitlyn's secret for 43 years.
Linda Thompson
In January 1981, Caitlyn tied the knot with actress, former Miss Tennessee and ex-girlfriend of Elvis Presley, Linda Thompson in Hawaii.
Linda walked down the aisle with Bruce as soon as the divorce with Chrystie was finalised.
The couple had two sons together, Brandon and Brody Jenner, but in 1986 they split after a five-year marriage.
In 1982, Bruce famously posed shirtless on the cover of Playgirl magazine alongside Linda, epitomising the manly ideal of a strong athlete.
Kris Jenner
Towards the end of 1990, Bruce met Kris Kardashian, the estranged wife of famed LA attorney Robert Kardashian.
When Kris' divorce was official in 1991, the new couple married the following month, with all eight of their children from their two previous marriages attending the iconic ceremony.
Caitlyn became stepparent to Kris's four children: Kourtney, Kim, Khloe and Rob Kardashian .
The Jenners welcomed two more children together, Kylie and Kendall.
Kris was married to Caitlyn for more 20 years, and the two raised a family through the pressures of fame.
Keeping Up With The Kardashians premiered in 2007 and the family's fame continued to reach an all-time high.
In 2015, Kris and Caitlyn split for good after 23 years of marriage, following months of rumours.
The pair were on good terms up until the release of Caitlyn's memoir, The Secrets of My Life.
In her explosive interview with Vanity Fair in 2015, Caitlyn made her first appearance as herself.
She slammed Kris and their relationship, saying: "I think in a lot of ways she became less tolerant of me. Then I'd get upset, and the whole relationship kind of fizzled."
Caitlyn told the magazine the reason behind their split was "20 gender and 80 percent was the way I was treated".
Sophia Hutchins
They've been notably reluctant to put labels on their romance, but Caitlyn has reportedly been dating fellow transgender star Sophia Hutchins for nearly two years.
The couple are thought to live together in Jenner's lavish Malibu beach home.
Last year, Caitlyn's 23-year-old girlfriend spoke out about their rumoured relationship and confirmed the pair are dating and that it might lead to marriage.
There has been speculation towards the Pepperdine graduate's relationship with Caitlyn, who is four times Sophia's age.
In August 2018, Jenner finally broke her silence about the reported relationship. She told Variety that the two were very close.
The pair's friendship was originally described as being like 'mother and daughter' but has developed into something more serious.
This comes as a stark contrast to what Caitlyn said in an episode of her since-cancelled reality show I Am Cait.
She said: "To be honest with you, I can't see myself dating women in the future.
"I've been there done that. I've got three very strong ex-wives. I just don't see it."
Family feud
Unfortunately, there was a lot of collateral damage following Caitlyn's divorce from Kris and a lot of drama surrounding the release of her memoir.
Kris had issues with the way she was portrayed in the book and many of her daughters supported the Kardashian matriarch, leading to a feud in the family.
Kris revealed she was 'done' with Kaitlyn after reading about herself.
As a result, Caitlyn still hasn't met Khloe's daughter True or Kim's newest arrival Psalm, and she's spent a limited amount of time with her granddaughter by Kylie, toddler Stormi.
An insider spoke of the feud last year: "Caitlyn was really hoping to reconnect with the Kardashians, especially with Khloe and Kim having had babies, but sadly she hasn't met them, and she hasn't even got to spend much time with her new granddaughter Stormi.
"She just wants some companionship and really felt all alone before she met Sophia."
The transgender star recently celebrated her monumental 70th birthday with her nearest and dearest but Khloe and Brody were nowhere to be seen.
Joining the former Olympian for the evening was her daughters Kylie, 22, and 23-year-old Kendall - from her marriage to Kris - as well as step children Kim , 39, and Kourtney, 40.
Caitlyn's son Brandon, 38, from her first marriage was also in attendance but his brother Brody, 36, was absent alongside siblings Burt Jenner, 41, and Cassandra Marino, 39.
Khloe's relationship with Caitlyn has been reportedly strained since she slammed Kris in her memoir.
However, earlier this year, Khloe appeared to suggest that their problems were in the past after confirming things were “fine” between the pair.
Caitlyn, who is still dating Sophia, is reportedly set to head to the I'm A Celebrity jungle this year after agreeing a staggering £500,000 fee.
