Megan Fox threatens to sue over "naked" photos
But the photos on Celebrity Jihad are completely fake, with Megan's face photoshopped onto the body of a woman with no clothes on.
The pictures are accompanied by rude captions, with one reading: "Megan Fox appears to pose naked in just a pair of high heel shoes in the sl*tty photo."
According to TMZ, new mom Megan's legal team has fired off a cease and desist letter, insisting the shocking images are immediately taken down.
A rep for Celebrity Jihad has told TMZ: "While we appreciate Megan Fox's concern for her image, we find it hard to believe that a woman who spent two "Transformers' movies bent over with her breasts pressed together could have her reputation damaged by a blatantly satirical website."
The site also has a recent picture of Megan when she was pregnant, which they've captioned "Megan Fox Looking Fat In A Bikini."
Megan recently gave birth to her first child, so it's no surprise she's not amused by the fake X-rated pictures.
The "Transformers" star and husband Brian Austin Green became parents to a little boy named Noah at the end of September, but have only this week confirmed the happy news.
Megan wrote on Facebook: "We have been very lucky to have had a peaceful few weeks at home, but I would like to release this myself before others do.
"I gave birth to our son Noah Shannon Green on September 27th. He is healthy, happy, and perfect.
"We are humbled to have the opportunity to call ourselves the parents of this beautiful soul and I am forever grateful to God for allowing me to know this kind of boundless, immaculate love.
"Thanks to those of you who wish to send your positive energy and well wishes. May God bless you and your families abundantly."
