Elton John wants to adopt more children

John told The Guardian, "I think it's difficult to be an only child, and to be an only child of someone famous.

"I want him to have a sibling so he has someone to be with. I know when he goes to school there's going to be an awful lot of pressure, and I know he's going to have people saying, 'You don't have a mummy.'"

He continued, "It's going to happen. We talked about it before we had him. I want someone to be at his side and back him up. We shall see."

John and his partner, David Furnish, fathered one-year-old Zachary through a surrogate mother.
