CANNES-Pop diva Lady Gaga has denied she will appear in a much-publicised upcoming film about singer Dionne Warwick in which she was said to be set to play the soul legend's British "nemesis" Cilla Black. Warwick appeared at the Cannes film festival Friday to promote the biopic, "Dionne", revealing that former Destiny's Child member LeToya Luckett would play her while Gaga would be Black, who died last year.–AFP

But Gaga's publicist immediately shot the idea down, telling the film industry bible Variety in comments published Saturday that she is "not attached to this project".

The casting had promoted much online speculation -- and hilarity -- over how the American singer would replicated Black's strong Liverpool "Scouse" accent.
