Late pop star Sonny Bono had an unusual nickname for his daughter before she grew up and underwent a sex-swap operation - he referred to little Chastity as "Fred."
Chastity underwent a sex change and legally became a guy called Chaz last year, and he has now revealed his father, who died in 1998, christened him with a male name early in life.
He tells TV host Jay Leno, "He called me Fred... We were in Palm Springs (California) one weekend, and there was this toy store that I used to love to go. We were in there looking, I don't know if it was mugs or key chains - stuff that had people's name on them.... They never had my name, so my dad said, 'Pick a name - what do you think of Fred?' And I apparently really liked it. It stuck for quite some time."
Sonny Bono never lived to see Chastity become Chaz - he died in 1998 at the age of 62. He split from Chaz's mother Cher in 1975.
