Jessie J has warned of the dangers of using online networking websites, branding them "mentally unsafe" for youngsters.
The Price Tag hitmaker insists the world of social media has become increasingly dangerous as it fuels bullying and means children can even be tormented while sitting in their own home.
She tells British newspaper The Observer, "Children used to get bullied at school. Now they go home and that's where the problem starts, because they sit on their phones all night, thinking about who's 'liked' a photo of them, who hates them, who loves them.
"They don't know what's real and what's not, editing their lives constantly to fit other people's views."
