Charlize Theron: The HRC Ally For Equality Award Winner!

Fresh off of a pair of panel appearances at WonderCon, Charlize Theron got glammed up before arriving for The Human Rights Campaign (HRC) Los Angeles Gala on Saturday night (March 17).

The Oscar-winning actress worked the arrivals area in an elegant black Acne frock as she joined "Hardball" host Chris Matthews and Marriott International, Inc. Executive VP Kathleen Matthews as the ceremony's Ally for Equality Award winners.

With the swanky fete being hosted by Chelsea Handler, the night also included special appearances by "True Blood" stud Joe Manganiello and Los Angeles Mayor Antonio Villaraigosa .

As for the organization, The Human Rights Campaign envisions "an America where gay, lesbian, bisexual and transgender people are ensured equality and embraced as full members of the American family at home, at work and in every community."

On a sidenote, during Charlize's appearance at WonderCon earlier in the day she was asked about her experience as a parent to newly adopted son Jackson, of which she told ET that it is "overwhelmingly incredible."
