Hollywood actress Jennifer Lopez has filed a $10m lawsuit against her first husband after he threatened to release steamy footage of them “in sexual situations”.

In happier times: Jennifer Lopez and her ex-husband, Cuban-born Ojani Noa, in 1997

Ojani Noa is planning to sell a show-all movie about their marriage, which includes clips from saucy home videos.

Noa — who J-Lo married in 1997 and divorced a year later — is looking for backing for his movie, entitled How I Married Jennifer Lopez: The J-Lo And Ojani Noa Story. No doubt about it, it's a catchy title.

Mum-of-two J-Lo has filed a lawsuit at Los Angeles County Superior Court claiming the move represents a direct violation of a confidentiality agreement she and Noa signed a few years ago.

Lopez — now happily married to Latino singer Marc Anthony — claims Noa intends to market “11+ hours of previously unseen home video footage of Jennifer Lopez and Ojani Noa”.

The Monster-in-Law actress was reportedly told that the footage depicts her “in a revealing lack of clothing, and in sexual situations, especially in the hotel room from [her and Noa's] honeymoon”.

Lopez, 40, is suing Cuban-born Noa for breach of contract and invading her privacy. She is seeking $10m (£6m) and wants a judge to ban the planned release of the movie and video footage. Lopez, in court papers, says she's suffered “shame, mortification, hurt feelings, embarrassment [and] humiliation”.

“I'm going to fight this,” Noa has vowed. This is not the first time he has tried to embarrass her.

Two years ago he threatened to write a tell-all book unless he was paid $5m. Instead, J-Lo was awarded $545,000 after a judge ruled that the book violated a 2004 deal not to publish details of their relationship. The book was not published.
