ET has confirmed Sonny Bono and Cher's child, Chastity Bono, is in the process of transitioning from a female to a male.

Chastity is in the early stages of the gender reassignment and started the process earlier this year following his 40th birthday.

Bono's publicist told ET, "Yes, it's true -- Chaz, after many years of consideration, has made the courageous decision to honor his true identity."

"He is proud of his decision and grateful for the support and respect that has already been shown by his 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," the rep went on to say.

The rep also asked for the media to respect Chaz's privacy, and noted that he will not be doing interviews at this time. Keep checking ETonline for more on this story.
