Chaz Bono hit the red carpet at the Sundance Film Festival for the premiere of the new documentary Becoming Chaz.
"I'm really excited to be here," Chaz told INSIDE EDITION.
Chaz was joined by his girlfriend Jennifer Elia, Rosie O'Donnell, and stepmom, Congresswoman Mary Bono.
But where was Cher? The Burlesque star couldn't make it as she was in Las Vegas performing in her one woman show.
The documentary, airing later this year on the Oprah Winfrey Network, follows Chaz as he goes through the difficult process of transforming from Sonny and Cher's little girl into a man.
Chaz shows his body after breast removal surgery, and shows him instructing his girlfriend how to inject the hormones he must take every day, practicing with an orange.
Also at Sundance, we spotted Elizabeth Olsen, the younger sister of twins Mary Kate and Ashley. She was there promoting two films she's starring in, and she credits her big sisters for supporting her.
"I think I had the best childhood ever, and I have a great family," said Olsen.
