INSIDE acquitted murder mom’s shocking new life as a live-in housekeeper for lawyer who got her off.

Casey Anthony is working as a live-in housekeeper for one of the lawyers who helped get her acquitted of killing her daughter, The National ENQUIRER has learned.

The shocking revelation comes as she faces more legal trouble after being sued by the law firm that negotiated a failed book deal about her life.

America’s most hated mother remains a virtual recluse inside a mansion owned by one of her attorneys, J. Cheney Mason.

Anthony disappeared from public view in July 2011 after a jury acquitted her of her two-year-old daughter Caylee’s murder.

But she could face new legal woes for failing to claim her domestic duties in Mason’s Longwood, Fla., home as income in bankruptcy papers that she filed in January 2013, according to Rick Namey, author of the just-published book, “Casey’s Ghost.”

“She’s staying in his house and acting as a housekeeper – and working there,” said Namey, a former public relations consultant for Mason. “The value of that accommodation has to be ascribed as income on the bankruptcy application and it’s not!”

“She has to live constantly on guard. She can’t go out in public,” he told CNN.

But according to documents filed with the Tampa Division of the Bankruptcy Court in Florida, Anthony claimed she’s been unemployed for four years and lists her income at zero dollars.

She faces up to five years in jail and a $500,000 fine if she’s convicted of making a false statement in her bankruptcy filings.

Allan Watkins, the lawyer for the trustee handling Anthony’s bankruptcy filing, acknowledged that they are “looking into” Namey’s allegations.
