That's the picture painted of her by a former security guard, who alleges in a sexual harassment lawsuit that the pop star emotionally scarred him by exposing herself, insulting him and threatening to fire him over a Slurpee.
Fernando Flores, hired by the singer in February, is seeking an undisclosed amount for being "humiliated and traumatized" by Spears, whose life has been under the control of her father since a series of breakdowns.
In the Los Angeles Superior Court lawsuit, Flores claims Spears "made repeated unwanted sexual advances" and summoned him to her room at her house "for no other purpose or reason than to expose her naked body or near-naked body."
Spears also "engaged in numerous sexual acts" in front of him, during which he would immediately leave, the lawsuit alleges. Spears also engaged in sex acts in the presence of her two young children, Flores claims.
When she wasn't exposing herself to him, she was hurling profanities and insults at him, the suit says.
During an excursion to watch Alice in Wonderland at a Hollywood theater, Spears asked Flores to fetch him a Slurpee. When he told her there was a 15-minute wait, she allegedly snapped, "I want my [expletive] drink! God! I'm gonna fire your ass!"
The security guard claims he was ignored or mocked by his supervisors when he made complaints about her alleged sexual behavior. "You know you liked it," one of his bosses allegedly told him.
An attorney for Flores didn't immediately return a call for comment. A rep for Spears didn't return calls for comment.
