JLO is the richest person of Latin American descent in Hollywood according to Forbes, and the most influential Hispanic entertainer in the U.S. according to People en Español's list of "100 Most Influential Hispanics.
But Ojani Noa, a chef and model who was married to Lopez for less than 11 months, said he would fight back.
Los Angeles Superior Court Judge James Chalfant's order to Lopez's former husband will remain in effect until a court hearing on Tuesday, to determine whether to extend it.
Lopez filed against Noa on Friday, two years after she won a $545,000 judgment against him in a similar case involving a planned tell-all book.
In her latest lawsuit, Lopez said Noa was shopping around to film industry players a movie with footage of the couple in sexual situations, including their time in a hotel room during their 1997 honeymoon.
Lopez, who married singer Marc Anthony in 2004 and has two children with him, is seeking $10 million in damages and a court order permanently blocking dissemination of any video showing her and Noa in intimate situations.
The judge said he issued the temporary order because the proposed movie "How I Married Jennifer Lopez: The JLo and Ojani Noa Story" may violate an agreement between Lopez and Noa, in which he agreed not to disclose private information about her.
Noa, who came to court on Monday without an attorney, said that he was not dissuaded by the judge's ruling.
"I'm going to fight this," he said.
In 2006, Lopez sued Noa over his plans to publish a tell-all book about their life, claiming the book would violate the nondisclosure, "non-disparagement" agreement the two had previously reached. It resulted in a California judge ordering Noa to pay Lopez $545,000 for breach of contract.
In addition to Noa, the judge's order on Monday temporarily blocking distribution of the film applies to movie producer Ed Meyer, even though his attorney argued that Meyer was not bound by an agreement between Lopez and Noa.
Lopez starred in the 2002 movie "Maid in Manhattan" and had hit songs with "Jenny from the Block" and "Love Don't Cost a Thing".
