'Crocodile Rock' icon Sir Elton John has revealed that he fears his son will be subjected to bullying when he eventually begins school.

Sir Elton and his partner David Furnish welcomed their surrogate son, Zachary, back in 2010 and he has previously spoken out about how they plan to raise him given their high-profile situation.

Speaking to the Radio Times recently, the musician and father explained that being a child with a famous parent often sets you apart from your classmates, but a child with two well-known fathers might be even harder for the other students to deal with:

"Being the child of someone famous is a huge ball and chain around your ankles. It's going to be very difficult... At school other children will say: 'You don't have a mummy.'"

"We've come a long way but there's still homophobia and will be until a new generation of parents don't instill it in their children."
