According to the hysterical popstar the hackers have gained access to her social networks and email.
She tweeted: "I have been HACKED and this hacker has now activated my old fb and my email. And Is pretending to be me".
She then warned "PLEASE DO NOT send any personal info on DM's. RT RT (before they delete this)".
Mind you we suppose those tweets could have been from hackers.
The hack could potentially put Jessie's 3.6m Facebook fans and nearly 2m Twitter followers at risk of online scams, so if Jessie tweets you any links to "LOLTASTIC" videos of last night we'd advise holding off on clicking for now.
