I can’t believe that Amy Winehouse has stooped to this level.

Amy Winehouse has been reduced to crawling up to resort guests and stealing their drinks — after fed-up resort staff refused to serve her. The sneaky singer also begs guests to order booze for her at the all-inclusive Caribbean resort.

Amy, who has fought addictions to drugs and alcohol, is at the posh Le Sport Spa on the sunshine isle of St Lucia for a health retreat.

Each day seems to start with good intentions as she limbers up with yoga-style stretches before swinging into action on exercise rings.

A source at the resort said:

“We keep catching her crawling past bars, or hiding behind chairs. She grabs guests’ drinks and runs off, like a squirrel with a nut.”

The Rehab star also baffles guests with her mood swings. But by lunchtime bikini-clad Amy is relaxing with a drink on the beach or even openly smoking joints by the pool.

Come nightfall, she is hitting the bottle with pals — despite the booze ban agreed by her management and staff.

But Amy — who has extended her two-week stay for another TWO MONTHS — was overheard on her mobile reassuring her father Mitch, 57: “I’ve been eating well and I feel great. I’ve only had a few drinks, Dad — honest.”
