The representative of Duff, 26, has contacted FBI after she was named among the 100 celebrities, including actress Jennifer Lawrence and model Kate Upton, whose alleged nude photos were leaked this week, reported the Daily Mirror.
"Photos claiming to be Hilary Duff are completely fake. They are all from the neck down and absolutely fake. They do not have Hilary's defining birthmarks or tattoos. We have alerted the FBI that these photos are fake," the representative said.
The FBI are already hunting the hacker and the agency said it was aware of the allegations concerning computer intrusions and the unlawful release of material involving high profile individuals, and is addressing the matter.
