A third, posthumously-released album of all new material from fallen R&B singer Amy Winehouse will arrive in stores some time in December, according to a spokesman from Island Records.  Titled "Lioness: Hidden Treasures," the 12-track record will contain a mix of alternate versions of Winehouse classics and all-new material, all previously unreleased except for Winehouse's cover of the soul classic "Body & Soul" with Tony Bennett, which was included on his album, "Duets II."

The album will hit stores on December 5th, and $1.60 from each album sold will be donated to the charitable foundation set up in the singer's name by her family following her death.  Winehouse died in her London apartment on July 23rd at the age of 27.  A coroner rules last month that the cause of her death was accidental alcohol poisoning, the culmination of her years-long battle with drug and alcohol addiction.
