My Sister’s Keeper star Cameron Diaz said she thinks women are "afraid" to say they don’t want children.
Cameron, 36, recently split with model Paul Sculfor, 37, and admitted she isn’t planning to become a mum just yet.
Asked if it depresses her that she is always asked about marriage and children, she said: "It doesn’t depress me, no.
"It’s just in our society, that’s what you’re supposed to do. I think women are afraid to say that they don’t want children because they’re going to get shunned.
"But I think that’s changing too now. I have more girlfriends who don’t have kids than those who do. And honestly? We don’t need any more kids. We have plenty of people on this planet."
However, Cameron said she hasn’t ruled out having children herself. She said: "I never say never. I don’t know what’s going to happen.
"I could end up adopting half a dozen kids, or I could end up being the next ‘octomum’ – who fricking knows! Or I might just make my nieces and nephews take care of me when I’m 80.
"But I don’t worry about what other people want for me. I just have to focus on what I want for myself."
Cameron also said she has never felt the Hollywood pressure to stay thin. She said: "Even when I was modelling at 16, I didn’t feel pressure to be thin. I mean I was thin, but there were girls thinner than me.
"Modelling’s tough at a young age, though, as you’re always being ‘chosen’ or someone else gets chosen over you. It breeds insecurity."
