Amy Winehouse is reported to be living of a diet that consists exclusively of sweets and fizzy drinks.

Friends of the singer, who is currently recording her third album, have raised concerns about her obsession with junk food.

"It is so, so sad to see the state she's got into. Those who see her on a daily basis are at a complete loss as to what to do,” a friend told the Daily Star.

"She is lost and bewildered and all she lives off is fizzy drinks and sweets."

In an interview with Rolling Stone earlier this year, one journalist described talking to Winehouse as she ate a banana and crisp sandwich at her home in Camden.

Recent reports claimed Winehouse was struggling to write material for her as-yet-untitled new album, which will be the follow-up to 2006's 'Back To Black'.
