Anyone who hasn't heard of Caitlyn - or Bruce - Jenner has been clearly living inside a whale. The announcement and transformation that took place in 2015, through a Vanity Fair cover story no less, was the single biggest transgender event in recent history. This is the story that brought the transgender community to the front and center of everyone's minds, and changed the landscape forever.
Of course, Bruce Jenner was no stranger to headlines before that. Winning the men's decathlon at the 1976 Montreal Summer Olympics, he was instantly hailed as "an all-American hero", and launched a career that spanned modelling, car racing, TV shows, film, writing, and - of course - Keeping Up With The Kardashians. With KUWTK, he was in the limelight once again, and ready to steal the show.
