Hoff knew for 30 years that Jenner wanted to be a woman

David Hasselhoff claims he has known for 30 years that Caitlyn Jenner wanted to be a woman.

The 'Baywatch' actor has been friends with the former Olympian - who was known as Bruce Jenner before her transition - for several decades and was baffled when he learned his pal had begun taking female hormones in the 1980s.
