Jonathan Shalit represents some of the biggest stars in the UK and said it was triggered by an online abuse campaign against her.
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 former N-Dubz singer is currently on bail after being arrested over claims she acted as a go-between in a drug deal.
She was arrested alongside musician Mike GLC in June after a newspaper claimed the pair had set up a drug deal in London's Dorchester Hotel.
The pair were arrested on suspicion of being concerned in the supply of class A drugs.
Both deny the allegations.
