All the Single Ladies
These famous, fabulous over-40s aren't afraid to forgo nuptials and nappies.
• Cameron Diaz (40)
The actress told InStyle magazine that she likes to go with the flow, saying: "Society definitely puts pressure on women . . . I don't know what's going to happen in my life! I could end up adopting children, I could end up with a partner who already has children, who knows?"
• Kim Cattrall (56)
The Sex and the City star realised motherhood wasn't for her. She says: "I realised that so much of the pressure I was feeling was from outside sources and I knew I wasn't ready to take that step into motherhood. Being a biological mother just isn't part of my experience this time around."
• Renée Zellweger (43)
The Bridget Jones actress split from actor Bradley Cooper last year, but has long been vocal about not wanting children, telling David Letterman: "Motherhood has never been an ambition. I don't think like that."
