N-Dubz singer 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 country's biggest stars said the former X Factor judge had also been targeted by "horrific abuse" online.
He told the Edinburgh television festival this evening:
The singer is currently on bail to late October following her arrest over claims she acted as a go-between in a drug deal.
