Hoax -- somebody took an article about Billy Joel and plugged in Mandy's name. I think it originated at the Perez Hilton board.
Quote:
Billy Joel has checked himself into a substance abuse and psychiatric hospital for a "personal problem", it has been revealed. The Grammy-winning singer entered the Silver Hill Hospital in New Canaan, Connecticut, to get help but no specific details of his condition have been released.
A statement from his record company, Columbia, said: "Billy Joel recently checked himself into Silver Hill Hospital for a planned 10-day stay to deal with a specific and personal problem that had recently developed.
"Joel scheduled his stay in Silver Hill several weeks ago and expects to leave in a few days, as planned."
Mariah Carey was admitted to the same hospital following her emotional breakdown in 2001.
