Some new photos have been unleashed of pop stars Katy Perry and Madonna in V Magazine, and they are rather naughty to say the least.

Is Katy Perry Moving In With Robert Pattinson?

On Saturday, Daily Mail posted the images that show the two singers with an old-fashioned look as they do certain things to each other that one might find strangely appealing. In one image, Perry is wearing a tight white dress with a fur coat as she ties up Madonna's hands with rope. In another picture, Madonna is bent over on all fours staring into the camera as Perry sits on top of her with her legs spread.

The Birthday singer mentioned that this shoot was pretty challenging for her body.

Is Katy Perry Getting Serious With Robert Pattinson?

"I was sore in my upper body and in my butt area from all that squatting," she said.

Madonna responded to this by letting her photo shoot partner know the positive benefit of that pose.

"It's good to be sore in your butt," she said. "My neck is sore from that wonderful moment when I was sucking on your heel."

The 80's icon also revealed that her sexual ways of expressing herself are a part of who she is and her father is learning to accept it.

I think he's finally come to terms with it. It's only taken 30 years," she said. "He's like, 'Do you have to simulate masturbation on the bed? Do you have to?' Yes, Dad, I do."

Perry mentioned that she hasn't reached that point although that idea won't be completely excluded.

"I haven't gone that far yet, but maybe under your great mentorship I might reach that point," the pop star said.
