Jennifer Lopez is suing mad – to the tune of $10 million - over her first husband's plans to include footage of their sex life in a proposed movie about their relationship

The actress and singer has launched a legal bid to block Ojani Noa's planned documentary 'How I Married Jennifer Lopez: The JLo and Ojani Noa Story' from seeing the light of day.

She is out to stop the model/chef from making public "11+ hours of previously unseen home video footage of Jennifer Lopez and Ojani Noa", according to court documents.

According to her lawsuit, filmmaker Ed Meyer - who is also being sued - warned Jennifer's lawyers that the footage shows the superstar "in revealing lack of clothing, and in sexual situations, especially in the hotel room footage from their honeymoon".

Her lawsuit insists the footage will cause her "irreparable harm" with the damage "difficult or impossible to measure" - but "not less than $10,000,000".

This is not the first time Jennifer - who is married to husband number three Marc Anthony -  has sued Noa over his plans to cash in on their 11-month marriage.

She sucessfully prevented him from releaseing a tell-all book in 2006.
