Caitlyn Jenner came out as a transgender woman in 2015 at the age of 65, but her son Brandon wishes she'd been able to do it a lot sooner for the sake of her happiness and their relationship.
In an interview with The Observer, Brandon explained that she had begun to transition following on from her divorce from his mother Linda Thompson in 1986, but went on to have some surgeries reversed as Caitlyn decided "it wasn't the right time".
He told the publication: "As her son, I wish my dad had been able to transition sooner, not only because I think she would have been happier, but because I think we could have built a stronger relationship earlier. Now, I’m making up for lost time."
Brandon also detailed how the relationship between his parents fell apart when Caitlyn began to date Kris Jenner, whom she went on to have daughters Kendall and Kylie with.
He shared: "[His mother, Linda] had worked hard to accept that the reason [Caitlyn] couldn’t be with her was because he was working towards transitioning. When he started dating Kris Jenner, whom he would go on to marry, that line of reasoning fell apart.
"It was tremendously painful. The effect of my parents’ souring relationship was that I didn’t see my father more than half a dozen times between ages eight and 25."
The Olympic athlete came out as a transgender woman in an April 2015 interview with Diane Sawyer, before her iconic "Call me Caitlyn" Vanity Fair cover was released months later.
Brandon was the first of Caitlyn's children she told about her transition, and he noted he was "so happy" for her.
The 70-year-old has since gone on to star in her own reality series and has made many TV appearances including being a contestant on I’m A Celebrity...Get Me Out Of Here! in 2019.
One of her stranger cameos has seen her recently pop up in BBC show All Round to Mrs Brown’s.
