Lady Gaga is godmother to both of Sir Elton John's children.

The legendary singer and his husband David Furnish, 50, were so impressed with Gaga's job as godmother to their firstborn son Zachary, two, that they have asked her to perform the same duties for Elijah, three months.

Elton, 65, told 'Extra': "She's a great role model, she's young, [and] she's been a great godmother to Zachary. We're all bonkers in this business, but we're human beings at the same time."

The couple also revealed that having children has changed their lives in every way.

David said: "You learn so much about yourself and about life by seeing children," while Elton added: "I love getting up in the morning and having breakfast with Zachary. Everything I thought I would find annoying about having children, like screaming and shouting and tantrums...I don't find any of it annoying. I find it all enchanting."

David has previously revealed how happy he is to have Lady Gaga guiding Zachary because he feels she has much to teach the youngster.

He said: "Zachary's going to inherit an incredible musical legacy from his father one day, and she will be a good person to guide him through the ins and outs of the music business, 'cause she sure knows everything about the business now."
