Heather Locklear has been placed on a 5150 psychiatric hold after reportedly beating up her boyfriend.
Locklear, 57, was taken to a hospital after her therapist determined that she was having a mental breakdown, TMZ reports.
The Hollywood star was at her home, and a third party called 911 for her before she was taken to hospital, the New York Post reports.
Locklear's representative did not immediately return a request for comment. There have been conflicting reports about whether her boyfriend, former American Motorcycle Association motocross racer Chris Heisser, was actually there at the time.
A spokesman for Ventura County Sheriff's Department told Page Six: "Deputies responded to a medical call at Ms. Locklear's residence yesterday afternoon. There was no crime, and we have no additional information to release".
