More pictures from Katy Perry and Madonna's V magazine photoshoot have been released.

The two superstar singers recently teamed up for a bondage themed shoot alongside photographer Steven Klein.

A number of images were released this week, with Perry for example seen pulling Madonna's hair.

A few more pictures have now been unveiled from the raunchy shoot, with the Queen of Pop for instance showing off a lot of cleavage.

Speaking about the shoot, Perry said: "I was sore in my upper body and in my butt area from all that squatting."

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

The photos feature in the summer issue of V magazine and it goes on sale this weekend.
