Chaz Bono legally changes gender

A judge approved Chaz Bono's petition for a gender and name change on Thursday, reports People.

The social activist was born Chastity Bono to parents Cher and Sonny. Chaz began a female to male sex change last year.

"Chaz couldn't be happier," said Kristina Wertz, legal director for the Transgender Law Centre.

"This is an important step in his transition and will allow him to change a variety of his identity documents to show who he truly is."

The 41-year-old filed the formal petition to legally change his name and gender last March.
