Chaz Bono, daughter of Sonny Bono and Cher, is no stranger to the media glare. As a toddler, then a girl named Chastity, he was a regular guest on the Sonny and Cher Show in the 60s and 70s. Now, at age 42, Chaz Bono is the subject of a new documentary called Becoming Chaz, where he allows cameras to capture his transition from female to male. He joins Madeleine to talk about the film and his new book.
