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.'
