The Grammy winner presented her son with the Stephen F. Kolzak Award for his OWN documentary, Becoming Chaz.

"I don't have anything prepared because I was so nervous, because my pronouns for my child just jump all over the friggin' place," joked Cher, who referred to Chaz as "she" several times throughout her speech. She went on to praise her only child, saying, "Chaz has the most courage of anyone I know."

The Stephen F. Kolzak Award is given to a gay, lesbian, bisexual or transgender entertainer for promoting equality. Modern Family's Jesse Tyler Ferguson and The Hunger Games star Josh Hutcherson were also in attendance for the event. They accepted outstanding comedy series and the Vanguard Award for increasing "visibility and understanding of the LGBT community," respectively.
