The 'Price Tag' star tells fans not to pay attention to any direct messages.
Jessie J has expressed frustration after her Twitter account was hacked earlier today (24th January).
In a message on both Twitter and Facebook, the 'Price Tag' star said the hackers had managed to activate her old accounts and email.
She went on to warn fans not to divulge their personal details if asked.
Jessie J wrote: "I have been HACKED and this hacker has now activated my old fb and my email. And Is pretending to be me.
"PLEASE DO NOT send any personal info on DM's. RT RT (before they delete this)."
Earlier this month, Lady Gaga was the subject of a similar Twitter hack.
Meanwhile, Jessie J is currently celebrating her second week at number one on the Vodafone Big Top 40 with 'Domino'.
