Gaga, who was raised Catholic, has never been one to shy away from exploring the topic of religion in her work, but with “Alejandro,” she seems to have pushed things to the limit. In the video, she and director Steven Klein combine Catholic imagery with sexual themes like S&M and androgyny. In one scene, LG wears a latex version of a nun’s robe, and in another, she sucks on rosary beads. Already, the clip has drawn complaints from the Catholic League and, somewhat surprisingly, Katy Perry, who wrote on her Twitter account Tuesday: “Using blasphemy as entertainment is as cheap as a comedian telling a fart joke.”
