Elton John: I'm worried about Lady GaGa

Sir Elton John is worried about Lady GaGa's health.

The 'Rocket Man' singer, 65, said he is concerned about the 26-year-old singer and her tiny frame.

He told The Guardian: "I look at GaGa and I think, 'How does she do it?'"

He also admitted that her parents are anxious about whether she is taking correct care of herself while travelling the world.

Elton continued: "I talk to her mum and dad about it. They worry."

The music legend explained that the star - who is godmother to he and civil partner David Furnish's son Zachary - is especially on their minds because she works extremely hard.

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."

Elton suffered his own health scare recently (23.05.12) . He was admitted to hospital with a "serious" respiratory infection.

He had to cancel shows in Las Vegas to recover from the illness.

He said in a statement: "All I can say to the fans is sorry I can't be with you. I hope to see you soon at this wonderful theatre at Caesars Palace."
