And the 'American Horror Story' actress - who has children Tara and Alexander with second husband Anthony Newley and Katyana with third spouse Ron Kass - called on the "strong" women in Hollywood to help out those in less privileged positions.
Speaking about her oldest daughter, who worked in a women's refuge for three years, she told The Observer magazine: "My daughter Tara is a pioneer for women's rights.
"These women in the refuges are having to hide their identities. They've got children and babies and then the husbands try to find them. I remember Tara was crying to me about a year and a half ago because one of the women had gone back and been murdered - that's what happens. Women are abused all over the world. Everybody's very adamant and strong and #MeToo here in Hollywood, but I don't see them opening refuges for women who have been abused."
Meanwhile, Joan - who married fifth husband Percy Gibson in 2002 - claimed her role as Alexis Carrington on 'Dynasty' was cut short because of her high salary.
She said: "I became the highest-paid woman on television only on the last season, and when I reported to work, they said, 'Oh, you're only going to be in 10 episodes because we can't afford you now.'
"I thought that was a bit mean. But then it's a very harsh town, this - you've got to have balls of brass. And you have to be able to absolutely take rejection."
