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 Friday.
