Chaz Bono, the son of Cher and Sonny Bono, will sit down tonight with Entertainment Tonight's Mary Hart for his first on-camera interview since publicly announcing he would be transitioning from female to male. Via People.com comes this quote from the interview:

"Still not anywhere near what I will look like, but really for the first time I am feeling much more comfortable with how I look physically," he says. "The most important thing about this for me is that my outsides are finally starting to match my insides," Chaz tells ET. "I feel like I'm living in my body for the first time, and it feels really good."

TMZ reported last month that Chaz had signed a deal with publisher Dutton to have his memoir, "Coming Clean," released in Spring 2011.
