Troubled singer Amy Winehouse has been banned from a pool at her luxury resort on St. Lucia over fears she will drown during a drunken late-night swim.

The Back to Black hitmaker has been on an extended break in the Caribbean since December (08) as she battles her drink and drug addictions.

Her father Mitch told last month (Jun09) how the singer has kicked her drug habit but is still drinking heavily.

Now staff at the Cotton Bay complex, where the singer is staying, are so worried about her fondness for swimming when she is drunk, they have banned her from the pool.

A source tells British tabloid The Sun, "Staff have found Amy on a number of occasions collapsed on the grass by the pool after going for a swim.

"There are concerns that one night she won't be able to get out of the water and something tragic will happen. She's regularly drinking large quantities wine and rum and no one in her condition should be going anywhere near water."
