The N-Dubz singer was yesterday cleared of all charges as the high-profile case collapsed

Singer and television personality Tulisa Contostavlos is to discuss her recent drugs trial in a new documentary.

Broadcast reports that the programme, Tulisa: The Price Of Fame, could air as soon as Monday (July 28) and will see her talking about the trial – which yesterday (July 21) collapsed – as well as the drugs sting, set up by undercover reporter Mazher Mahmood.

The trial, which started last week at Southwark Crown Court, came to an end after Judge Alistair McCreath stated that he believed prosecution witness Mazher Mahmood lied to the court at a pre-trial hearing.

Undercover reporter for The Sun On Sunday, Mahmood pretended to be a film producer and met up with Contostavlos on a number of occasions, promising to get her film work. He then asked the N-Dubz singer to broker a £800 drug deal. However, because of McCreath’s suspicions of Mahmood lying to the court, Contostavlos will walk free, as will her co-defendant Michael Coombs, 36, who had previously pleaded guilty to supplying cocaine.

Contostavlos spoke outside of court, following the case’s collapse. “I have never dealt drugs and never been involved in taking or dealing cocaine,” she commented. “Mahmood has now been exposed by my lawyers openly lying to the judge and jury. These lies were told to stop crucial evidence going before the jury.”

Mahmood has since been suspended from The Sun.
