Fatherhood changed Elton John for better

The 69-year-old, who has two sons - Zachary and Elijah born to a surrogate - with his partner David Furnish, says he could never imagine how his world has changed since the children's arrival, reports femalefirst.co.uk.

"It's unimaginable how the children have changed my life. Years ago I couldn't imagine becoming a dad, but the kids have changed me so much as a person and for the better," John told Closer magazine.

"I love them more and more every day and being a dad is now the most important thing in my life," he added.
