Elton John has revealed that he is worried about Lady Gaga's health.
The 65-year-old singer said that he is concerned about the singer's tiny frame.
He told The Guardian newspaper: "I look at GaGa and I think, 'How does she do it?'"
He added: "She is frail, and she doesn't eat when she should, and she's a girl, and it's tougher for a girl. She works really hard. She will be in Denmark one night and Saudi Arabia the next. I know how tiny she is and I do worry about her, yes."
John added that the popstar's parents also worry about whether she is taking care of herself when travelling across the world.
He continued: "I talk to her mum and dad about it. They worry."
Gaga is godparent to Zachary, Elton John and David Furnish's son.
