Nas pays tribute to the late Amy Winehouse in his new music video.

The tragic singer - who died last July aged 27 - appears from beyond the grave by singing in the rapper's latest song "Cherry Wine," with her image projected onto a brick wall. The tribute ends with a black and white image of Amy with the words, "In memory, Amy Winehouse (1983 - 2011)," and Nas believes the track came directly from "God and Amy."

"It was chilling. A feeling of bitter sweetness, wishing that she was here. The director was genius. My main concern was being able to put her in the video in a respectful way," Nas told The Daily Star.

Nas has hit back at critics who claim he was cashing in on Amy's death by using her image: "I'm gonna write for my sister, that's what we do. If what had happened to her happened to me I would have expected the same from my friends."
