Amy Winehouse not collaborating with Lady Gaga

Singer-songwriter Amy Winehouse's publicist has brushed off reports that she is collaborating with Lady Gaga for her highly anticipated comeback album.

Lady Gaga is preparing to release her long awaited third album, the follow-up to 2006's Grammy award winning "Back to Black", after a four-year hiatus which saw her battle drink and drug problems, reports dailystar.co.uk.

A tabloid had recently reported that the "Poker Face" singer had even offered flying to London so that she could make music with Winehouse - to ensure her upcoming release is a success.

But Winehouse's representative has refuted the rumours, insisting that the claims are "not true at all".
