Heather Mills is considering adopting a child.

The 42-year-old former model - who has six-year-old daughter Beatrice with ex-husband Sir Paul McCartney - would love to have another youngster to look after, but thinks the world is "too overpopulated" to want to get pregnant again.

She told the Daily Express newspaper: "I wouldn't have another child because the world is already too overpopulated. But I might adopt one."

Charity campaigner Heather - who has her own vegan restaurant, V-Bites in Brighton, South East England - also spoke of how her young daughter is already following in her famous mother's footsteps when it comes to animal rights.

She said: "She goes up to people in restaurants and says. 'You know that's a baby cow?' People must think that is what I tell her at home, but it's not."
