Amy Winehouse may never release another album

London, Sept 20 : Troubled singer Amy Winehouse has given pals and fans cause for worry, as she has failed to come up with a single song even after spending six months in the studio.

Winehouse's pals fear that she may never release another album again, with the two unfinished tracks that followed after her 2006's Grammy award-winning Back To Black.

The 25-year-old singer's friends feel that with her drug problems not abating she would never be fit enough to record the third album she was supposed to release this year.

"With all the problems surrounding her personal issues and addictions we are really concerned it will never get finished," the Sun quoted a source as saying.

"If six months produces two half-baked tracks how long will an album take?

"Unless she sorts herself out and gets some focus it might never happen," the source added.

Winehouse had returned to the studio with Salaam Remi, who masterminded her 2003 Mercury Prize-nominated debut Frank.
