A photoshoot featuring Madonna and the sheep from her estate in Wiltshire dyed different colors has angered animal rights campaigners.
The star is pictured on the front of Vogue alongside a flock of sheep, colored blue, pink, yellow and green.
A spokesman for the Royal Society for the Prevention of Cruelty to Animals (RSPCA) said: "Why is it necessary and what are they trying to prove? It is an irresponsible publicity stunt."
Madonna's people insist the dye is temporary and the sheep weren't harmed.
