Amy Winehouse has been banned from swimming amid fears she will drown.

The troubled singer's excessive drinking has caused concern for those close  to her and now worried staff at the St Lucia resort where she is staying  have warned her to stay away from the pool.

A source explained to Britain's The Sun newspaper: "She is regularly  drinking large quantities of wine and rum and no one in her condition should  be going anywhere near water.

"There are concerns that one night she won't be able to get out of the water  and something tragic will happen."

Management imposed the band on the 'Rehab' star after a series of  near-misses for the singer.

The source added: "Staff have found Amy on a number of occasions collapsed  on the grass by the pool after going for a swim."

Earlier this week, it was reported staff at the resort have had her villa  fumigated because she keeps adopting stray dogs.

A source said: "Management initially turned a blind eye to what Amy was  doing. But she's adopted about five or six dogs now. They're all strays  without the proper vaccinations and they all have fleas.

"The management did not want the risk of any of the fleas infecting any of  the other rooms, so they got a firm of fumigators in to blitz Amy's quarters  and told her not to bring any more animals on site."
