London, Apr 13 : Troubled English singer Amy Winehouse is driving her record bosses ballistic, as she is busy fooling around with the Gorillaz rather than working on her third album.

Though the Universal record bosses spent a huge amount on making Amy return to the Caribbean in a bid to help her "focus her mind" on her forthcoming album, their efforts have gone in vain because she has not yet stepped into the studio.

Winehouse has not yet stepped into the studio with producer Salaam Remi, who was behind her hit album `Frank'.

Instead, the `Back to Black' hitmaker has been busy trying out stuff with Damon Albarn and his band of Gorillaz.

According to sources, the Universal bosses are already infuriated with Winehouse, as she has not been able to make a single up market song.

"They were not happy to say the least. They want Amy to get cracking on her new album, but the results have so far not been up to scratch," the Mirror quoted a source as telling 3am.

"Imagine how they felt when they realized she had agreed to work with Gorillaz? They couldn't believe it. It's an unnecessary distraction. They think she should invest all her energy in her own music. She should be knuckling down and delivering the goods," the source added.

On the other hand, Winehouse, who has become a fan of Gorillaz style of music, is livid that her record bosses are not humming the same tune as her. (ANI)
