The group say that the singer used their tuxedo-wearing giant eye image during her most recent tour, and they haven't gotten any recognition for it
Ke$ha's most recent tour saw her dancing in front of a chorus line of tuxedo and top hat wearing men with oversized eyeball masks covering their face. The costumes worn by the backing dancers seem to be inspired by the veteran rock group, The Residents, but the avant-garde art collective are claiming that not only did Ke$ha steal their idea, but she hasn't given the group any recognition for the image.
Her on stage routine does look mightily similar to The Residents
The Residents aren't looking to sue Ke$ha or anything, all they want is some recognition and a thank you from the singer for inspiring the look. Ke$ha has been spotted wearing a Residents t-shirt in the past - during an interview with MTV - and is probably a fan of their work, and the band are simply asking for some recognition from her for using their image during the stage show.
