AceShowbiz - Amy Winehouse has sparked fears for her planned comeback following the publication of a shambolic new magazine interview in which she "gulped wine" and struggled to answer basic questions. The singer has remained largely out of the spotlight over the last few years as she battled drug problems and a broken marriage, but is attempting to get her career back on track by launching a fashion line and working on a new album.

But a new article printed in Britain's Harper's Bazaar magazine, which features Winehouse's first official interview in months, has fuelled concerns for the troubled star. The "Black to Black" hitmaker was seen "gulping down a big glass of wine" during the photoshoot with rocker-turned-photographer Bryan Adams and later became "physically unstable" and "wobbly", according to the magazine.

Journalist Polly Vernon also alleges that during the interview, Winehouse was unable to focus, mumbling "vague", incoherent responses throughout the chat. She concludes, "I quickly realize, I am unlikely to get any answers. She is just not... present. She is distracted and vague. My most straightforward questions confuse her."
