Katy & Madonna for V–They’re two of the world’s most famous pop stars and now they pose together for the summer issue of V Magazine. Katy Perry and Madonna star in a bondage inspired shoot styled by Arianne Phillips for the publication’s new issue which is out on newsstands on Memorial Day, May 26th. Steven Klein, who frequently works with Madonna, photographed the shoot where the singers are shown wearing leather, retro coifs and dark red lips. Katy, who rocks green hair in the images, says about the physicality of the shoot, “I was sore in my upper body and in my butt area from all that squatting.”
