Jennifer Lopez has sued her former chauffeur Hakob Manoukian for at least $20 million, claiming Manoukian tried to extort and defame her, reports E! Online.

Lopez is alleging Manoukian threatened to reveal "disruptive and potentially damaging" information about her unless she paid him $2.8 million, the story notes.

She claims that an attorney representing the driver, who sued Lopez, her manager Benny Medina and Marc Anthony for breach of contract in April, demanded the money or Manoukian would disclose information he allegedly overheard while working for her, the piece notes.
