Party girl Amy Winehouse must stay in the hospital after collapsing at her London home the other day, because test results have proved inconclusive. Medics were called to her home yesterday after the 24-year-old star fainted and her father Mitch demanded she be taken to a hospital as "a precaution." But test results have proved inconclusive, and Winehouse has been ordered to stay in hospital for at least one more night. A spokesman for the star says, "Doctors want to get to the bottom of it before releasing her. There will be further tests and they will keep her under observation. She seems to be fine… but they are taking their time to be sure." The representative adds that Winehouse had been signing autographs for Canadian fans who had been waiting outside her house all day when she fainted. We wish this talented singer would get her act together. She could end up as the next Janis Joplin, and that would be very sad.
