British pop star Tulisa Contostavlos' manager feared she would commit suicide following her arrest on suspicion of supplying drugs. The singer was taken into custody in June (13) and charged after she was allegedly caught on camera setting up a cocaine deal worth $1,200 (£800) for an undercover reporter from The Sun newspaper. The scandal hit the star hard and prompted her to cancel all planned gigs over the summer, and her longtime manager Jonathan Shalit reveals he ensured security guards were at Contostavlos' home to keep an eye over her. Speaking at The Guardian Edinburgh International Television Festival in Scotland on Friday (23Aug13), 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 genuinely thought her life was over." He also blasted the former N-Dubz star's online critics, who took aim at her through social networking sites as the backlash from her arrest ensued. Shalit added, "People give opinions day in and day out on social media, particularly when you're young, and so the vileness that attacks you is horrific. "I think it's worse now if you're younger because young people completely live their life through social media. People take it very personally what social media says. They don't realise it's disposable immediately and they really believe it." Contostavlos remains on police bail alongside her rapper pal Mike GLC, who stands accused of selling the illegal substance.
