No, this isn't an old story we mixed in with today's news - it happened again. British singer Amy Winehouse was hospitalized after fainting.

Said her rep: "Amy Winehouse 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 took her to hospital as a precaution. Doctors are unsure of the cause, and Amy is currently undergoing tests."

The 24-year-old Grammy winner "may be kept in [the hospital] overnight for observation," said the rep, with father Mitch Winehouse by her side.

This is just the latest in a long string of troubling Amy Winehouse incidents.

In May, the wife of Blake Fielder-Civil was released on bail after being arrested for suspicion of drug use and following a barroom melee.

Winehouse was also questioned by police for more than nine hours about footage from January that shows her allegedly smoking crack.

She also went to rehab in January, and has since taken the lead over Britney Spears in The Hollywood Gossip Death Watch by a big margin.
