JENNIFER LOPEZ SUED BY EX-HUSBAND'S GIRLFRIEND

This is crazy....

RadarOnline.com reports that Lopez, 41, is being sued for $10 million by Claudia Vazquez, the girlfriend of her ex-husband Ojani Noa.

Apparently J.Lo's ex and his new girlfriend have had plans to create a motion picture out of old home videos that Noa has of Lopez. The footage allegedly shows Lopez naked, and she understandably wants to put the kibosh on their film project. So Lopez's attorney reportedly sent Vasquez (who's listed as a co-producer on the project) a cease and desist letter regarding the tapes.

But Vazquez claims that Lopez misstated the facts to the court to obtain the restraining order that interferes with their movie project. In short, Vasquez wants to cash in on the J.Lo tapes, and she's annoyed that Lopez isn't allowing that to happen. She's rumored to be filing the lawsuit in L.A. on Wednesday.

But this isn't the first case of drama between the two women. It seems Lopez and Vaquez (who has been dating Noa for 10 years) may have had bad blood for years.

"Vazquez has met Jennifer Lopez on many occasions. They hate each other," Ed Meyer, another man involved in the film project, told RadarOnline.com. "Jennifer Lopez called her a 'whore' to a Univision reporter last year."

But Meyer also believes that it's not Lopez's desire for privacy that's motivating her to shut down their project -- but, instead, the rumored long-standing rivalry.

"We believe that this entire lawsuit against Ojani and I over the movie and the sex tape home videos centers around Jennifer Lopez's hatred for Ojani Noa dating Claudia Vazquez," he said.

This also isn't the first time Lopez has had to deal with Noa since the end of their six-month marriage. In 1997 the singer-actress was paid more than $500,000 by Noa as he "violated their marital settlement confidentiality agreement" by attempting to write a tell-all book.
