In a statement, her spokesman said: "Amy was at home this afternoon when she briefly fainted.
"Fortunately, her manager's assistant was there to stop her falling.
"She quickly recovered and her father, Mitch, took her to hospital as a precaution.
"Doctors are unsure of the cause of the incident and Amy is currently undergoing tests.
"She may be kept in overnight for observation."
He added: "They want to make sure she is OK but it wasn't an emergency dash."
To me what is scary about this story is not her going to hospital, but her hands. How did they get all yellowed like that? Back when I was a smoker my fingers turned that color, but the whole hand. That is just so horrifying. Hopefully they will look at her hands while she is there. So ewwwww.
