The former 'The View' host is said to be the latest celebrity to have had intimate photographs stolen from her and posted on the internet, prompting her to get federal investigators involved.
A spokesperson for the star said: "A small number of photos are of McCarthy that were stolen from her hacked phone account.
"McCarthy's representatives are reporting the theft to the FBI and contacting all websites posting the photos to demand the immediate removal of all personal and private photos of her, including nude photos.
However, despite contacting the FBI, the 41-year-old beauty - who recently married Donnie Wahlberg - is insisting that the most revealing images are in fact fakes.
Her representative told E! News: "Certain photos claiming to be hacked photos of Jenny McCarthy and posted to various websites are not McCarthy at all, but someone else, including the most explicit nude photos.
"Other photos are stills from a comedy skit from her TV special, 'Dirty, Sexy, Funny'."
In keeping with other a number of other stolen photos of celebrities in various states of undress, Jenny's pictures first emerged on websites 4chan and Reddit.
