(From ABC News) Chastity Bono, daughter of Cher and the late Sonny Bono, is undergoing gender reassignment surgery, his publicist confirmed to ABCNews.com.
"Yes, it's true -- Chaz, after many years of consideration, has made the courageous decision to honor his true identity," Howard Bragman said. "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.
"We ask that the media respect Chaz's privacy during this long process as he will not be doing any interviews at this time," Bragman added.
UPDATE: Human Rights Campaign (HRC) and the Gay and Lesbian Alliance Against Defamation (GLAAD) have each released statements about Chaz Bono's gender transition.
"This announcement by Chaz is nothing short of courageous. His decision to be public about his transition speaks to the courage he has in living his life openly and honestly, and will also undoubtedly help foster much-needed dialogue about the lives of transgender Americans and the need for full equality," said Human Rights Campaign President Joe Solmonese. "It is our hope that all of us can feel great pride that we live in a country where each one of us has the ability to be true to our own identity. From the time we are born, we are taught that there are girls and there are boys. But like our history, our communities, are rich with people who have blurred, blended or crossed those lines. Chaz is now part of an impressive and remarkable group of Americans who have made our country a better place simply by being true to their selves."
"Chaz Bono's decision to live his life authentically represents an important step forward, both for him personally and for all who are committed to advancing discussions about fairness and equality for transgender people," said Neil G. Giuliano, president of the Gay & Lesbian Alliance Against Defamation ( GLAAD ) .
"Coming out as transgender is an extremely personal decision and one that is never made lightly. We look forward to hearing Chaz's story in his own words in the future.
"GLAAD encourages media outlets to cover this story accurately, and to avoid speculation about the details of Chaz's story before he is ready to tell it in his own words. The GLAAD Media Reference Guide urges media to use the name and pronoun preferred by the transgender person, in this case, referring to him as Chaz and using male pronouns."
