Jennifer Lopez is suing her former chauffeur for $20 million for his attempt to extort her and for character defamation.

Lopez's suit states that Hakob Manoukian "made written and oral demands that unless Manoukian was paid $2.8M, he would disclose sensitive and personal information that he had allegedly heard while driving Ms. Lopez," according to documents obtained by The Wrap.com.

The website reveals that Manoukian's then-attorney made the extortion attempt on Oct. 3, 2011. The former "American Idol" judge filed her documents in Los Angeles Superior Court on Friday.  

The 43-year-old singer/actress' lawsuit revealed that her former driver signed a confidentiality agreement. The legal document prohibits Manoukian from disclosing the "Dance Again" singer's personal and business affairs he may have heard. So his request for $2.8 million, according to her suit, means he "engaged in extortion, attempted extortion, breach of oral contract and breach of written contract."

E! News reports that Lopez's suit claims that Manoukian became "hostile and angry" toward her business manager Benny Medina and "plotted to retaliate" after he was demoted to being just a driver from the original title of Head of Security and Transportation. Manoukian was also disappointed with Medina for not selecting his recommendation for a new security team.

"In the furtherance of this plot, he abruptly terminated his employment with Ms. Lopez and began to threaten her," added the report.

Lopez's suit is a cross-complaint responding to Manoukian's lawsuit filed against Lopez and Medina earlier this year for fraud, breach of contract and wrongful termination. 

TMZ obtained a copy of Manoukian's lawsuit. The documents state that Medina "hated his guts from the start... claiming Benny would often rip him for the way he dressed, cussed him out in public and told him he could not speak English well enough."

Manoukian said he started driving for Lopez and her then-husband Marc Anthony in 2005 and that he was paid more than $200,000 per year to be their Head of Security and Transportation.

Medina responded to Manoukian's lawsuit through a statement to TMZ. Lopez' manager stated that their former driver was a "disgruntled employee who chose to quit."
