Oscar winner Helen Mirren is glad she has never had children and slams the notion childless women are sad as "bulls**t". The 62-year-old actress insists she is happier without kids and doesn't regret not having any of her own. She says, "I am thrilled that I don't have children - I have the thing I love, which is freedom. "In a funny way, if you don't have children, you can concern yourself more generously with the extended family and let other people have the children. "It's a bit of a guilty secret because as a woman, you're almost expected to be sad if you don't have children, but that's bulls**t. There have always been women who don't have kids."
