BLOODY MESS...

Rehabbing "Rehab" singer Amy Winehouse was a bloody wreck this week when she violently vomited blood all over her Caribbean hotel room.

Staff at the Jade Mountain resort in St. Lucia were horrified when they were sent to Winehouse's suite to clean up the mess. "There was blood and vomit all over the bathroom, it was just terrible," said one worker, according to Brit tabloid The Mirror.
