Chastity Bono to Have An Addadicktomy

Just call her Chaz from now on.

Cher is about to get a new son.

Chastity Bono, the celebrity offspring of the singer and late husband Sonny Bono, is changing gender from female to male, her publicist told the Daily News on Thursday.

The 40-year-old, known to family and friends as Chaz, came out as a lesbian nearly two decades ago. Bono intends to make the transition from woman to man, publicist Howard Bragman said.

"Chaz, after many years of consideration, has made the courageous decision to honor his true identity," Bragman said.

"He is proud of his decision and grateful for the support and respect that has already been shown by loved ones.

"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."

Bragman declined to answer any further questions about the sex change.
