Sir Elton John says his son's childhood will be tough because of homophobia at school and his superstar status.
The Rocket Man singer told Radio Times magazine that it will be 'very difficult' for one-year-old Zachary, who was born by a surrogate mother on Christmas Day 2010.
'At school other children will say, "You don't have a mummy",' said Sir Elton.
'We've come a long way, but there's still homophobia and will be until a new generation of parents don't instil it in their children.'
