Britney Spears is under investigation over assault charges after a staff member at her home alleged the singer struck her, authorities say.
Deputies went to Spears' home in southern California after the staff member reported the Monday night dispute, the Ventura County Sheriff's Office said on Thursday.
No one was injured.
Reports taken by deputies will be handed over to prosecutors for consideration, the sheriff's office said.
Spears' lawyer Matthew Rosengart said in an email the investigation was "overblown, sensational tabloid fodder - nothing more than a manufactured 'he said she said' regarding a cell phone, with no striking and obviously no injury whatsoever".
Spears has a home in Thousand Oaks, west of Los Angeles.
Spears, 39, hired Rosengart last month as she seeks to regain greater control of her life 13 years into a court conservatorship that has power over her money and affairs.
In court hearings, Spears called the conservatorship "abusive".
Rosengart has made his first priority removing Spears' father, James Spears, from his role as conservator of his finances.
James Spears said in a court filing last week that he planned to step down, but gave no timetable.
