The pop stars cover the latest issue of V magazine where they show off their sexy sides in matching S&M costumes. In one shot, Katy sits on Mag's back as she pulls her hair and in another snap Perry's got the "Material Girl" tied up on the couch.
The singers look nearly identical with their matching Bettie Page hairstyles, makeup and sexy getups, too.
The 55-year-old also opens up about what her family thinks of her wild persona .. telling the mag that it's taken 30-something years for her dad to adjust.
"I would always say, 'Dad, I'm an artist, I have to express myself. You don't understand,'" Madonna explains. "I think he's finally come to terms with it. It's only taken 30 years," the blonde beauty added. "He's like, 'Do you have to simulate masturbation on the bed? Do you have to?' 'Yes, Dad, I do.'"
The 27-year-old, on the other hand, hasn't gone that far yet with her public image. Katy's the daughter of a Pentecostal pastor, so we imagine she's had an even tougher time dealing with her family and fame.
"I haven't gone that far yet," the "Roar" singer says, while telling Madonna, "but maybe under your great mentorship I might reach that point."
The ladies definitely got into the photo shoot, though. "I was sore in my upper body and in my butt area from all that squatting," Perry says, referring to the sexy poses.
Madonna adding, "It's good to be sore in your butt. My neck is sore from that wonderful moment when I was sucking on your heel."
Well, it definitely seems like the stars have some real chemistry! What do you think about Katy and Madonna's risque spread?
