Amy Winehouse smoking banana skins

Amy Winehouse has picked up a new habit – smoking banana skins.

The 'Rehab' singer – who has battled drug addiction – took up the vice while spending time on the island of St. Lucia, where she is currently house hunting in a bid to escape the temptations of London.

A source told Britain's Daily Star newspaper: "Amy wandered onto a private porch on Cariblue Beach and began speaking to a group of locals who were smoking banana skins.

"She made sure there wasn't anything really bad in them because she's being so good now.

"They made one in front of her using dried strings from the inside of the peel instead of tobacco, and putting it onto a piece of rolling paper. She loved it and has taken to drying her own peel in the sun and smoking it in the evening."

Amy – who has previously admitted her favourite food is banana and crisp sandwiches – insists she has turned over a new leaf and put her drinking and drug habits behind her.

She is quoted as saying: "I'm clean now and feel much better for it. I'm just a normal girl now."

The singer's behaviour on the Caribbean island seems to reflect her words.

Looking tanned and relaxed, the 25-year-old star was seen barefoot riding a horse on the beach after tucking into a pizza.

Amy's record company have reportedly decided to embrace their star's quest to start a new life in St. Lucia – where she enjoyed a three-month holiday earlier this year – and are planning to finance a recording studio in her new home, so she can work on new tracks for the follow up to award-winning album 'Back To Black'.
