The singer says she "necked" painkillers and vodka while awaiting trial on drug charges

Tulisa Contostavlos has revealed that she attempted suicide following her involvement with a sting conducted by a reporter for The Sun last year which led to her being arrested on drugs charges.

The subsequent trial collapsed in court last week after Judge Alistair McCreath stated that he believed the reporter had lied to the court at a pre-trial hearing. The pop star, who was accused of brokering a £800 cocaine deal, walked free, as did her co-defendant Michael Coombs, 36, who had previously pleaded guilty to supplying cocaine.

In a new documentary to air on BBC3 tonight (July 28), Tulisa is shown explaining how the period in her life from being arrested to the trial reaching court left her feeling like an “emotional wreck”. In the documentary, the singer says: “I’d had a drink so everything felt even more intensified. I just picked up [the painkillers] and just necked them with a bottle of vodka. I don’t even know what I was planning to do.”

Talking about what drove her to the situation, Contostavlos says she thought: “I don’t have the energy any more to do this and even if I get through it, then what? I’m just going to be drained as a person. I’m going to be numb by the end of this. I don’t know how much of me I’m going to have left. And I was like, shall I just end it? Shall I just get on with it and just never have to feel like this ever again?”

Though an ambulance was called by her assitant, the singer did not require medical attention.

In a separate case, Tulisa was found guilty of assault last week. She has said that she will appeal her conviction for hitting a man at V Festival in 2013.
