Chastity Bono, the celebrity offspring of the singer and late husband Sonny Bono, is changing gender from female to male, TMZ.com reported Thursday.

The 40-year-old, known to family and friends as Chaz, came out as a lesbian nearly two decades ago.

Bono now intends to make the transition from woman to man, her publicist told TMZ.

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