Anastacia wants to have a baby.
The 41-year-old singer - who is single after filing for divorce from husband Wayne Newton in April after three years of marriage - insists she won't give up on the idea of having a child of her own within the next 20 years.
She said: "Having children has been a hope for me since I was very young.
"For a period of time when I was married, I was saying no, but I'd have to be 60 to give up hope."
The US star admitted she would consider adopting a child if she was unable to conceive a child naturally.
She added in an interview with Reveal magazine: "I would adopt, like Sandra Bullock. There doesn't have to be a father, a mother, two dogs and 2.5 children to be a perfect family."
The singer - who has previously battled breast cancer - insists she doesn't worry about her health these days but admits her biggest ambition for the next 10 years is to still be alive and healthy.
She said: "I don't worry about the cancer coming back. I have annual check-ups. If I worried abut it, I wouldn't be able to move on. We waste too much time worrying about tomorrow.
"When I'm asked where I want to be in five or 10 years time, I say I just want to be alive and healthy."
