Amy Winehouse is being urged to keep her behaviour in check after throwing a glass of water over a happy holiday maker in St Lucia.

The Rehab star - who has been seen frolicking topless in the sun with supposed new man Josh Bowman - was reportedly forced to apologise to the 27-year-old for her reckless actions.

The incident, which took place on Saturday, is said to be the last straw for many fellow guests who are fed up with Amy's disruptive behaviour.

A source tells The Sun, “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.”

Another source added: “Some staff have started singing their own version of Rehab under their breath when she’s around.

“But they altered the chorus to sing, ‘Just go, go, go’.”
