London, June 23 (ANI): Madonna is so worried about her obsessive fans that she reportedly orders sterile wipes of her dressing room after each show on her latest world tour.

According to the Mirror, the pop queen has set up a "sterilisation team" to clean away any traces of DNA that she might have left behind from her hair, skin or saliva, the Daily Mail reported.

And she is believed to have demanded that only herself and her entourage are allowed backstage and no one is allowed to even look at her dressing room once it has been made ready.
