Baaaaaaaad Madonna! Animal rights groups are pissed over a photo shoot from a few years back, where Madonna and Guy Ritchie dyed sheep different colors -- all for a great looking magazine spread. The shear insanity!

According to The Sun, Madge claims that they were just paying homage to photographer Cecil Beaton. The animal groups aren't buying it, calling it an "irresponsible publicity stunt." The RSPCA is sticking firm to the idea that the whole ordeal is sending the wrong message to others -- who might copy the stunt. It's unlikely Madonna's losing sleep over this one.

Baaaaaaaaaaaaaad!
