Cher’s child is in the process of having a sex change, it has been revealed.

Chaz Bono, who lived as a lesbian called Chastity for nearly 20 years, is to undergo gender reassignment.

His publicist Howard Bragman said last night: “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.”

LGBT organisations such as GLAAD have already given their support.

Bono, 40, is Cher’s only child with late husband Sonny Bono. He is a gay rights activist but also works as a musician, writer and actor. He wrote about his experience of coming out to his mother in the memoir Family Outing.

Bragman said he has already begun hormone therapy but it is not yet known whether he will be having gender reassignment surgery.
