It seems like Elton John is in total protector mode these days - of his own 17-month-old son, Zachary, and, it seems, world-touring rock stars.
The legendary British singer told The Guardian recently that he does sometimes worry about Lady Gaga's health.
"She is frail, and she doesn't eat when she should, and she's a girl, and it's tougher for a girl," the 65-year-old said of his 26-year-old friend's grueling performance schedule. "She works really hard. ... I know how tiny she is and I do worry about her, yes."
He's no stranger to the rigors of the business, but there are times, he said, when "I look at Gaga and I think, 'How does she do it?' I talk to her mom and dad about it. They worry."
But Elton John had to worry about himself on May 23, when he was hospitalized with a respiratory infection.
Now that he's better, the singer is apparently setting his sights on expanding his family with partner David Furnish. The self-described only child told the newspaper, "I want [Zachary] to have a sibling so he has someone to be with. ... I think it's difficult to be an only child, and to be an only child of someone famous."
And the fact that little Zachary has two dads is also a consideration.
"I know when he goes to school there's going to be an awful lot of pressure, and I know he's going to have people saying, 'You don't have a mummy,'" he said. "It's going to happen. We talked about it before we had him. I want someone to be at his side and back him up. We shall see."
