Nanny, Andrea Duncan, said she was treated like Cinderella while taking care of socialite Susan O’Leary’s adult daughter

A 31-year-old nanny is suing her former boss claiming that she scalded her with boiling water and forced her to wear sexy outfits while entertaining friends.

Andrea Duncan said she was hired on July 10 by New York City socialite Susan O’Leary to take care of her 23-year old daughter, Suzanne, who had “severe emotional disorders.”

Duncan said while working in O’Leary’s $8 million Carnegie Hill apartment earning $250 a week plus room and board, her boss flew into an unprovoked screaming rage in August and tossed a pot of boiling water at her, burning her abdomen.

The lawsuit, which was filed on Friday, says O’Leary prevented Duncan from seeking medical treatment and told her to “take more Adderall, drink wine and apply aloe,” for her pain.

Duncan, who says she is an aspiring model, claims that O’Leary threatened to fire her if she complained to anyone.

In addition, Duncan claims that her boss ordered her to go out on dates with her personal trainer and broker and to be “nice and accommodating to them,” or be fired.

She claims that after O’Leary fired her housekeeper, she was ordered to pick up the slack at no extra pay and when O’Leary hosted cocktail parties she was ordered to wear scantily clad outfits.

After six weeks on the job, Duncan said O’Leary fired her one day when she was showing someone the scar that was left by the scalding incident.

Not named in the lawsuit was O’Leary’s husband, Patrick, who is a spinal surgeon at the Hospital for Special Surgery in Manhattan.

Duncan said Dr. O’Leary was not living at the Park Avenue apartment while she was taking care of his daughter.
