The Steel Magnolias star's youngest son Sam was on hand to present the trophy to his mum at the HRC's 16th Annual National Dinner in Washington, D.C.
Field in turn thanked Sam, and paid tribute to him for having the courage to 'come out'.
She told the audience, ""(His) journey to allow himself to be what nature intended him to be was not an easy one... Nature made Sam. It wasn't a choice. He was always, always Sam. Glorious, smart, funny, sweet Sam. And finally at 20, long after he beat the c**p out of his brothers at tennis and he knew more than anyone about basketball, at 20 he was finally able to stand up proudly and say, 'I am a gay man.'
""You all (at the HRC) have fought for him as surely as if you were one of his parents. You've changed and are changing the lives of little boys and girls who realise somewhere along the way they're just different from their other brothers and sisters - and so the f**k what?""
