Amy Winehouse stunned holidaymakers in St. Lucia after throwing a glass of water over a fellow diner.

The 25-year-old singer - who is enjoying a relaxing vacation in a luxury resort on the Caribbean island - is said to have doused a female tourist in water while she was having dinner with her partner.

Following the incident, Amy refused to apologise to the 27-year-old woman but later changed her mind when the couple threatened to call the police and press assault charges.

Explaining the reasons behind Amy's actions, her spokesperson said: "Amy misunderstood a conversation and wrongly believed a slight was made. The matter has been resolved."

The confrontation is the latest in a series of events which have angered staff at the resort.

A source told Britain's The Sun newspaper: "Everyone wants Amy to disappear. Her attack on this guest was the last straw.

"She walks around in the same grimy bikini bottoms each day with her boobs on show, gets drunk, gropes waiters and is rude to male staff. She's hardly the most popular guest."

Earlier this week, it was claimed Amy had been violently sick over a breakfast buffet after a big night out. Her spokesperson has now denied the reports.
