Pop star Lady Gaga has settled with a former personal assistant who sued her to collect overtime she claimed she was owed for being on call constantly for over a year.

The settlement, revealed in a stipulation of dismissal filed by the parties’ attorneys on Monday in the Southern District of New York, came two weeks before the case, O’Neill v. Mermaid Touring, 11-9128, was set to go to trial.

The assistant, Jennifer O’Neill, befriended Gaga when the two lived in the same Lower East Side building. In 2010, Gaga, whose birth name is Stefani Germanotta, hired O’Neill as her personal assistant at an annual salary of $75,000.

O’Neill testified that she was expected to be on call “24/7″ and drop whatever she was doing if Gaga asked her to. O’Neill said she never had her own hotel room, that she and Gaga often shared a bed, and that Gaga would wake her up throughout the night to do things for her, like changing a DVD when she did not want to walk across the room to do it herself.

Last month, Judge Paul Gardephe (See Profile) denied Gaga’s motion for summary judgment, ruling that O’Neill may be entitled to pay for time spent on call but not actively working (NYLJ, Sept. 13).

Paul Millus, of counsel at Meyer, Suozzi, English & Klein, an attorney for O’Neill, would not comment beyond saying that the parties had reached a “mutually agreeable settlement.”

Steven Hurd, a partner at Proskauer Rose who represents Gaga, did not return a call for comment.
