Fresh off their fourth straight Emmy win for Best TV Drama, the cast of Mad Men got together Sunday to host the Rape Treatment Center Foundation luncheon at billionaire investor Ron Burkle’s historic Green Acres Beverly Hills mansion for the charitable cause.

Christina Hendricks, looking lovely in a St. John’s dress, exclusively told RadarOnline: “This is an extraordinary organization that I didn’t know about until recently.” Her character, Joan, was raped on the show and she said that having Mad Men showcase issues that are still socially relevant today is awe inspiring.

“I’ve never been prouder in my life. The show is extraordinary and not many shows touch on these subjects and bring to light and inspire a conversation about it afterwards. Not many shows have viewing parties where they discuss the issues.”
