On 2 June 2013, The Sun on Sunday ran a front page story on singer-songwriter Tulisa Contostavlos. The front page read: "Tulisa's cocaine deal shame"; this story was written by The Sun On Sunday's undercover reporter Mahzer Mahmood, who had previously worked for the News of the World. It was claimed that Tulisa introduced three film producers (actually Mahmood and two other Sun journalists) to a drug dealer and set up a £800 deal. The subterfuge involved conning the singer into believing that she was being considered for a role in an £8 million Bollywood film.
