Campbell, 43, who split from longterm boyfriend Vladimir Doronin last year, said she would love to have a family, reported Contactmusic.
"I do want to have children, whether I have a man or not. I will have it on my own," she said.
The British beauty, who has long been a campaigner for ethnic diversity in the modelling industry, also insisted that the fashion industry is not responsible for models suffering from eating disorders.
"You cannot blame our industry for the body type of women. The food issue is a really sensitive subject for me, and it makes me nervous to really talk about it because I've never seen a designer in my whole 28 years say to someone, 'Go on a diet, lose weight?'," she added.
