After a lot of speculation, Elton John has confirmed that Lady Gaga is his son's godmother. In an interview with Barbara Walters that was teased during "Good Morning America" Friday morning (April 22), the British music superstar, with his husband David Furnish by his side, opened up about his decision to name Gaga godmother to their son, Zachary.

"Yes, yes she is. When you get to the real person under there, there's a real simple person under there who loves her parents," he explained.

Furnish added, "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."

Talk of Gaga's involvement in Zachary's life began to surface earlier this year, but the couple wasn't in a hurry to confirm the reports. In a February interview, Furnish wouldn't confirm or deny whether Gaga was the godmother.

"We haven't publicly confirmed that yet but your sources are very good!" he said. "I prefer not to comment on it because we are going to make a statement about godparents later on."

When John hosted "Saturday Night Live" on April 2, he joked about Lady Gaga being his son's godmother. "For those of you concerned that we are unusual parents, do not worry. It's not like we are the only two people involved in the child's life. His godmother is Lady Gaga. That's true, that's not a joke ... which is ironic because I've always said that Mars ain't the kind of place to raise your kids. And Gaga loves Mars. She says Mars has good schools and great discos."

Elton was at the Tribeca Film Festival in New York this week to promote "The Union," a Cameron Crowe documentary about John's Grammy-nominated collaboration with fellow music legend Leon Russell.
