Elton John fears Lady Gaga\'s non-stop schedule will take its toll on her health. He admits he worries about the \"frail\" 26-year-old pop star, who is godmother to his son Zachary, as she travels for her Born This Way Ball tour. \"I look at Gaga and I think, \'How does she do it?\' I talk to her mum and dad about it. They worry,\" contactmusic.com quoted John as saying. \"She is frail, and she doesn\'t eat when she should do, 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,\" he added. India times.
