Bruce Jenner, now in his 60s, occasionally appeared on the show as the stepfather of the girls, who were infamous for their shallow, high-spending lifestyle.
In 2015, Jenner, now 66, revealed on a TV interview that he was becoming transgender, changing from a man to a woman, with the help of doctors.
Jenner also changed his name from Bruce to "Caitlyn", and began dressing as a woman and wearing women's cosmetics.
Fans of his previous career as an Olympic champion were shocked, and reactions of his 6 children (from three marriages), were mixed.
The story was incorporated into "keeping up with the Kardashians", and Caitlyn is currently starring in her own reality show "I am Cait."
Jenner has been hailed as a hero (heroine ?) for bringing attention to transgender issues in the US.
As for why she changed, Cait says she never felt comfortable as a man, and is now living as her "true self."
