Elton John has confirmed that Lady Gaga is godmother to his baby son Zachary.

The star mentioned Gaga while he hosted US show Saturday Night Live.

In an opening monologue, he told the audience: “It’s been a very exciting time for me. Just a few months ago my partner David and I became the proud parents of a beautiful baby boy. As you can see, I still haven’t lost the baby weight!

“For those of you concerned that we are unusual parents, don’t worry, it’s not like we are the only two people involved in the child’s life. His godmother is Lady Gaga… That is true, it’s not a joke.”

Both stars had refused to confirm whether Gaga was Zachary’s godmother.

John appeared as himself in a sketch which poked fun at the Royal Family.

The Queen, played by Fred Armisen, said: “You know when I see a Candle in the Wind? When I light my farts!’

John joked that she was a “mean old bitch”.
