Chastity Bono Changing From Woman to Man

Chastity Bono, daughter of legedary singing duo Sonny and Cher, is no longer Chastity.

TMZ reports that Bono, an author and musician, is changing her gender from female to male -- and, as a transgender male, is now Chaz.

The process began shortly after Bono's 40th birthday.

"Chaz, after many years of consideration, has made the courageous decision to honor his true identity," Bono's publicist, Howard Bragman, told TMZ.

"He is proud of his decision and grateful for the support and respect that has already been shown by his loved ones," Bragman said. "It is Chaz's hope that his choice to transition will open the hearts and minds of the public regarding this issue, just as his 'coming out' did nearly 20 years ago."
