The film, entitled 'Amy Winehouse Out-Raps Kanye West for Zalon LOL!!!!!', has been posted on the video-sharing website YouTube.

It shows Winehouse performing alongside Zalon – a member of her backing band – and two other musicians called Ade and Robin.

In one section of the freestyle, Winehouse can be heard saying: “Mitch, I know better, I would never wear my hair out.”

The video is not the first time Winehouse has posted a bizarre video on YouTube.
