Katy Perry’s “Black Widow” demo has leaked in full. As some of you may remember, the song was co-written by Perry and went on to be recorded by racist has-been “rap” artist Iggy Azalea and features pop songstress Rita Ora. “Black Widow” would go on to peak at no. 3 on the Billboard Hot 100 in Summer 2014. The leak comes almost exactly 6 years since the song was officially released as a single (July 8 2014).
