Jennifer Lopez is suing her former driver for extortion.

The former 'American Idol' panelist is claiming he demanded $2.8 million or else he would tell the media and authorities about secrets he overheard while driving her around for jobs.

Jennifer's case is a countersuit to a claim filed by Hakob Manoukian, who claimed he was forced to resign after being publicly berated by her manager, Benny Medina.

In her countersuit, obtained by website, Jennifer alleges Hakob became drunk with power and wanted to control her entire security team and get more money for doing it. When he was turned down, Jennifer claimed he retaliated by threatening to spill confidential information that would be highly embarrassing.

Jennifer says the driver threatened that if he wasn't paid $2.8 million he would take his information to authorities and have her criminally prosecuted.

She is suing for damages in excess of $20 million.

Meanwhile, Jennifer is reportedly on the verge of breaking up with Casper Smart.

The 43-year-old performer has apparently come to the realisation that she really doesn't have a lot in Common with her 24-year-old backing dancer, and is beginning to feel like his babysitter.

A source said: ''Jen is currently on tour with Enrique Iglesias, and Casper is the head choreographer of her show in which he also dances. It's tough being on the road - this isn't Jen's first tour and she has been feeling more like Casper's babysitter than girlfriend.''
