The lawsuit in Los Angeles County Superior Court accuses Ojani Noa of intending to sell a movie containing hours of home video, including some of the actress in sexual situations taken on their honeymoon.
Lopez and Noa were married for 11 months in 1997. She claims he's violating a prior confidentiality agreement.
Lopez wants at least $10 million and a court order preventing Noa and filmmaker Ed Meyer from releasing the material.
A Facebook message left for Noa was not immediately returned.
In 2007, Lopez won $545,000 in another lawsuit that blocked Noa from publishing a ghostwritten tell-all book.
The lawsuit was filed on Friday.
