He’s become known as the patriarch of one of Reality TV’s most well-known families – The Kardashians.

But Bruce Jenner, 65, was a star long before Kim, Khloe, Kourtney, Kendall and co were on the scene.

Bruce is a gold Olympic medal holder after winning the decathlon in the 1976 Summer Olympics held in Montreal.

He’s made headlines recently over reports he is undergoing gender reassignment to become a woman. After months of rumours, Bruce is about to sit down with ABC’s Diane Sawyer in an exclusive interview to reveal all.

We take a look at Bruce Jenner’s story so far in pictures:
