Sir Elton John has spoke about how his life changed since becoming a father to Zachary.

In a chat with Daybreak, the pop star spoke about how he and his partner David Furnish wanted a child and how fatherhood has changed them.

He said: "It's the most wonderful thing you could possibly go through. He's changed our lives. Everything is about him now. He's the icing on the cake.

"The first thing I do every morning is have breakfast with him. He shares my breakfast. Whatever I have, he wants. He has my boiled egg and I have his pineapple and vice versa."

The singer also told Daybreak's Helen Fospero why writing his his first book, 'Love is the Cure' on Aids and HIV, was an emotional experience.

He said: "I wanted to do something about aids. There's lots of facts in the book but it also tells you why why I changed my life."

Elton John's new album Elton John vs Pnau are storming towards Number 1 according to the Official Albums Chart Update.
