ISIS extremists have encouraged supporters to poison the food she buys from the supermarket.
'We know what she eats – poison it!' wrote the message to ISIS followers along with a picture of the Duchess.
They also threatened to attack husband Prince William according to The Daily Star.
'Intelligence agents believe the threats made against Kate are not idle and are linked to messages sent by Husnain Rashid.’ The publication wrote.
'It's a disgusting plot as it involves Kate's young children, and hits out at her attempt to live a normal life like any mother wants to.'
Husnain hit the headlines when he was jailed for life for calling on ISIS supporters to attack Prince George.
During his court appearance, evidence showed that he had sent messages along with a picture of the young prince.
'Even the royal family will not be left alone.'
He added: 'School starts early.'
