Reagan has filed a countersuit that claims Jameson signed an agreement last April giving Regan Media the "exclusive right" to negotiate with TV networks on any project involving the "screen performer," the New York Daily News reported Wednesday.
However, Jameson -- aka Jenna Massoli -- claims a TV deal with the A&E cable network was in the works before the deal was signed. She alleges her husband, John Grdina, told Regan of the discussions with A&E, "clearly identifying the project as one which they were pursuing on their own."
Regan Books published Jameson's memoir, "How to Make Love Like a Porn Star: A Cautionary Tale," last summer.
