Pop superstar Madonna has once again upset animal lovers by dyeing her sheep in various shades.

Apparently, Madonna has dyed the sheep in shades of blue, pink and yellow for a Vogue Living photo spread, reported Madonna clarified that the dye was temporary and that it did not harm the animal. However, activists are afraid that this might inspire others to do the same and they may not be so careful. Madonna and her husband, British film director Guy Ritchie, were criticised in the past for hosting pheasant-hunting parties in their estate.
