Tulisa 'Was On Suicide Watch' After Arrest
Former X Factor judge Tulisa Contostavlos was put on suicide watch by her manager after newspaper reports that she had been involved in a drug deal.
Jonathan Shalit, who represents some of the UK's biggest stars, said the singer had also been targeted by "horrific abuse" online.
Speaking at the Edinburgh Festival, he said: "She got to the point I was worried she would commit suicide.
"I made sure that someone was at her house for two consecutive nights to make sure she did nothing stupid, because she was literally at that point of she genuinely thought her life was over."
The 25-year-old is currently on bail until October following her arrest over claims she acted as a go-between in a drug deal.
She was held along with 35-year-old musician Mike GLC in June after they went to a police station in central London by appointment.
The pair were arrested on suspicion of being concerned in the supply of Class A drugs after a Sunday newspaper claimed that Contostavlos had introduced a journalist to an alleged supplier.
Half an ounce of cocaine changed hands as a result of the alleged deal carried out at London's Dorchester Hotel, according to reports.
Mike GLC, who will answer bail in October, has insisted that he and the former N-Dubz singer are innocent.
