Sir Elton John is worry about Lady Gaga's health. She is going to perform in three stadium shows in Auckland. He told The Guardian: "I look at GaGa and I think, 'How does she do it?' "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." "I talk to her mum and dad about it. They worry." Source
