Why Madonna donned creepy face mask?

The mystery behind Madonna's creepy face mask that the singer wore during a spooky show in New York has been revealed.

The 57-year-old singer grabbed the utmost attention by sporting white creepy mask, which covered her face (bar two eye holes) with an equally quirky T-shirt with jeans, News.com.au reports.

The 'Like a Virgin' hit-maker along with her kids Lourdes Leon and Rocco Ritchie were seen clambering into the vehicle wearing casual outfits.

The US stage show was based on Shakespeare classic 'Macbeth'.
